Google, gmail, you tube, etc SUDDENLY cannot load in Firefox on Mac but work fine in Safari on same Mac.

I get this message:Did Not Connect: Potential Security Issue

I have Firefox 139.0.1

This was working this morning but stopped in the afternoon. I use Duck Duck Go but I also tried switching to Google browser but got nowhere. Firefox loads everything else just fine. But no Google related sites.

I have deleted history, cache, cookies. Restarted the Mac. Closed and reopened Firefox. Again, all other sites accessed, just not anything related to Google.

I can see gmail on Firefox focus on my Ipad that is on the same internet connection as the Mac. This is really annoying.

Hello. I have noticed the following problem with your browser: at some point, if you have several resource-consuming tabs open (this is a subjective assessment, I have not tested it), almost all the buttons in the browser stop working, namely the tab close button, the extension button, etc., but you can still close them using hotkeys. This problem goes away when you restart the browser.

I should say that this problem appeared not so long ago, about 1-2 weeks ago, when I updated Fedora 40 --> Fedora 42.

Please tell me where the problem might be.

I cannot get my Roboform Ext. to appear when needed to sign into certain sites or use my CC within my Roboform for purchases! I have all of the areas in the private browsing area, but the Extension still does not work!

After installing a Firefox updated on Tuesday, I've been having multiple issues. The first issue I ran into was being unable to log into a work account that I have been using daily for 2 years. I was able to fix that issue by disabling the Enhanced Tracking Protection for that specific page. I tried that same fix for my other issue, but it is not correcting it.

I use a program called signNow to upload documents and send to people to sign/countersign. Since this update, it's not working on Firefox. I tried it on Edge and it works fine. When I upload a document, it's just blank. No text, pictures or anything at all. See attached screenshot. I've tried several documents and none have worked, but all of them have worked in Edge. How do I fix this so I can continue to use Firefox?

Hi, I've encountered a problem where if any error occurs when you try to create a new calendar event (I.e. Thunderbird cannot connect to the CalDav server), it will give you an error pop-up and discard everything you have input.

Losing work like this is extremely annoying and I think what should happen when an error occurs is that Thunderbird would go back to the event creation popup, preserving everything that was input into it, and let you try to create the event again (perhaps save it into a different calendar).

I'm not sure if this is the best place to ask about this but it was the most easily accessible place I could find.

This happened in Thunderbird desktop version 138.

Hi why cant i get my taskbar to show up on firefox on full screen. I used to be able to just put my mouse on the bottom of the screen to see the clock now i cant. ty

I have used Thunderbird and its diary for years, and make extensive use of reminders in the diary (my memory is not what it once was!). Latterly, when deleting or postponing a reminder, Thunderbird goes into "not responding" mode for many seconds or even some minutes.

I have Thunderbird linked to both my gmail and my protonmail email accounts. If I look at Task Manager when Thunderbird goes unresponsive it seems to be the connection with protonmail that is the problem - see the attached screenshot.

Help, please

The game keeps freezing up on download. I keep refreshing it to try to download but fails multiple times . Sometimes I can eventually play the game thru its entirety. I have CC Cleaner on my laptop n use that . Today it cropped up that my Firefox was corrupted ?????

I have a fresh install of Firefox. (139.0), but I never not had this problem. I open up the application, open fb.com not scroll a bit not do anything I just wait for the page to load. I run top in terminal and plugin-container goes up to high heavens ~100% CPU. My battery gets hot, and drains infinitely faster than when not using Facebook with Firefox. I have a new M3 with 8gb ram. Lightning fast otherwise. Same problem with my older M1. (irrelevant but Chrome is burning up the CPU for the same reason) My best guess is that the end-to-end encryption is using too much power or whatever Facebook is doing to tap my every blink. Which is fine. I don't do anything excessively bad. The question is here if why can't I just give a certain percentage to the process? I accept the performance to drop a little but having a 120 degree laptop on my thighs at all times and having to charge it daily is not healthy and annoying. About the plugins/extensions I use here is the list of them: none. I have no extensions, plugins, themes, nothing. Brand new fresh install. I'm sure it's reproducible with any Facebook account with end-to-end encryption chat.

I set up a CardDAV addressbook link to my iCloud addressbook. Everything is fine, and syncing works great. After ~2 days, it stops working and I have to generate a new app-specific password, delete my addressbook, and re-establish a new link with the new app-specific password. I tried to turn on CardDAV login, but nothing it written to the logs.

Has anyone run into this problem and how do I go about troubleshooting it?

Hello All,

I seem to have a problem with Firefox freezing. I moved back again to Firefox to maintain the adblockers that Chrome so graciously crippled.

Now, with that out of the way, I noticed that sites that have autoplaying MPEG-4 files that basically act like good old-fashioned gifs tend to cause the firefox to freeze.

It is a strange freeze though - the whole browser becomes VISUALLY unresponsive, but if I click blindly, say to close the tab or if I scroll up or down it appears to work. How do I know? Well, if I drag the mouse to the bottom of the taskbar in Windows and bring up the thumbnail... It unfreezes the browser - showing the changes I made blindly, at least until it freezes again when the MPEG-4 files start playing again. The freezes are not temporary either - I need to unfreeze through this thumbnail method I described above - otherwise it stays frozen.

The issue is not consistent either. Sometimes it goes through the MPEG-4 files perfectly fine, but usually scrolling through any thread containing embedded MPEG-4 videos, like reaction clips and the like, is literally impossible due to the rate of freezes.

Furthermore - this issue does not seem to occur when MPEG-4 videos are embedded on site itself, but freezes occur when the files appear in comments on imageboards and such.

I have narrowed down the culprit - the issues ceases when I disable the hardware acceleration, but I do not find it to be an acceptable solution in a long term - because disabling it causes various videos to play at noticeably lower and unpleasant framerates.

I'm fairly convinced it is NOT a hardware or software issue on my end - it is a brand new and powerful PC with a fresh install of Windows 11 and all the drivers are up to date, AMD GPU. Unless the issue is with some obscure codec, perhaps. However, the issue does not persist on any other browser I used.

A few of my recently uploaded videos will not load in Google Photos in Firefox on my PC. I get a "Your video will be ready soon" message and endlessly rotating loading circle. They are mp4 files, but other mp4 videos taken just seconds apart load and play normally. I've tried clearing my cache and deleting and re-uploading the videos but it doesn't help. The problem persists when I load Firefox in Troubleshooting mode. The same files that won't play in Firefox load and play normally in Google Photos in Chrome on my PC and also on my android phone.

Bonjour,mon Imac 27 pouces sort de chez Apple il y a 10 jours,tout allait très bien,FireFox s'ouvrait en plein écran, et après une mise à jour de FireFox il y a 48 heures,comme à chaque mise à jour il ne s'ouvre plus en plein écran,je dois le mettre manuellement,ça commence à m'irriter sérieusement,en principe une mise à jour doit apporter de l'amélioration et c'est rétrograde pour moi. Comment faire pour que j'ouvre FireFox en plein écran automatiquement ? Merci

Over the last month or two, my PC has frozen, not crashed, just frozen, while I was watching youtube. I have left it for a few hours, but it does not unfreeze. I am forced to hard restart the PC. When I restart Firefox, the first thing it does is update. It only happens when I have a Youtube video running, Youtube can be open in a tab but not running a video with no issue. Is it possible that the update request is locking up my PC? Is it being caused by Youtube? Any suggestions on how to stop it happening short of changing browsers? No error messages. No crash report. Nothing in the reports file to point me in the right direction.
