I-Firefox Community Forum

4 rows of links working great and sync killed it all. Data is in the prefs.js file but firefox wont read it how can I fix this? Hours I have been chasing around with ai checking all the settings etc. wth? HOW HARD DOES THIS HAVE TO BE? please help before I uninstall and never come back. Wasted way too much time!

For some weeks now, the "File" menu randomly opens by itself then closes a second or two later. It seems to happen once I get focus on a page. For example, if I open a new tab then go to Google and ask a question, once the answer is returned, within a second or two the File menu drops down then closes again. I have the latest version of FF (149.0), 64-bit under Windows 10. There are a couple of settings in about:config that were suggested to be changed by ChatGPT but this hasn't made any difference.

Have 4 Gmail accounts... after repeated opening and closing one or two on my IMac, suddenly Gmail will not open login page. if I close Firefox and reopen it, all is fine. Tried several solutions including elimination of extensions, clearing cache, etc. all work for a few days then problem returns. Imac running Tahoe 26.4, Firefox auto update turned on. Wish to avoid creating separate Gmail pages.. I open Gmail from my bookmarks at top. TPlease try to keep it simple... I am an senior and OK with basic technology and wife (who has one of the Gmail accounts) is more limited in tech skills. Thanks

bold textEvery time I start the cimpouter I lose my bookmarks how can I avoid this issue. Each time i takes about two hours messing about to get them back

I am using Firefox 149.02 (64-bit).

I access the website The Daily Beast (https://www.thedailybeast.com) and like to make Comments on some of their articles. Up until about 2 months ago everything was running smoothly. But now I am unable to use the Comment section. I get the following response from The Daily Beast...

"Oops, something went wrong :( We detected some connectivity issues therefore we’re unable to load the Conversation."

I do not have this problem when using either the Norton Private Browser or the DuckDuckGo Browser.

What's wrong?

Downloaded recent Firefox update. Restarted PC. Logged into a site I use (and need this season). I could not even use a saved bookmark for login page. Cannot log in to it.

I added the site under Firefox settings option.

I tried logging in with Private mode, where I was able to use bookmark for login page. HOWEVER, I quickly experienced issues and got attached warnings. I reported 'site not working' on the debug option. While this usually immediately fixes a problem, it did nothing at all.

This is why I am always AFRAID of installing the "Updates" - I frequently lose functions. It takes as TREMENDOUS amount of time to fix them and there is no "help button" on Firefox or Mozilla to scan issue and fix it.

As of today, every single time I try to download something, Firefox instantly cancels it and I'm not sure what the issue is. I've disabled adblock and Malwarebytes and refresh Firefox—same issue. Hitting retry from the download panel works but I can't figure out why the first download attempt is always cancelling, even if it's the same file. I'm not even downloading big files.

I have for years disabled crash reporter on firefox, however it recently crashed 149.0.1 (64-bit) & sent info ANYWAY! it then upgraded to 149.0.2

WHY is this NOT being honored ? firefoxCrashOFF.jpg attached

Using cmd-tilde keys on MacBook Pro to change front viewed page no longer works reliably under Tahoe. Any workaround? Also, Firefox sometimes freezes Navigation between programs, and the only way to navigate is to quit Firefox. I'm on Tahoe 26.4 MacBook Pro 2023 M2 Max. Thanks.

I've got an Angular project running locally on my machine (https://localhost:4300 using NodeJS 24.11.1 and Angular 20.3.0) and I can't get it to consistently load files for me when I refresh the page.

The network call shows the response coming back, but I'm getting a red ban icon in the Status column instead of 200. Sometimes it's styles.css and nothing looks right. Sometimes it's polyfills.js and I get an error in the console about "In this configuration Angular requires Zone.js". Sometimes, it's one or many chunk-*.js files. Sometimes, it goes back and forth about which it doesn't want to load. And then sometimes, everything is fine. When it fails, it takes between 1 and 20-some-odd refreshes of the page to get it to load properly. The passage of time doesn't seem to make a difference, as sometimes I can recompile the project and jump right into Firefox and it loads fine. Other times, it will only load after I've refreshed multiple times. If it's a JS file that fails, I also see a warning in the console window about "Loading failed for the script with source [filename]".

I've added an exception for the SSL certificate. CTRL+F5 doesn't make a difference in the behavior. The only extensions I have running are LastPass and Bitwarden. The only plugins I have in place are "OpenH264 Video Codec provided by Cisco Systems, Inc." and "Widevine Content Decryption Module provided by Google Inc." I've disabled Enhanced Tracking Protection for the site. I've rebooted and restarted everything.

Any ideas what might cause this? The other developers on the team don't have this issue. I'm using "ng serve --host 0.0.0.0 --ssl xxx-app-name-xxx --live-reload false" to run my environment. What should I be looking for on my machine that might cause this type of intermittent failure?

I'm stuck in an endless loop in Firefox for Linux (MX Linux) whenever Cloudflare is used as security.

"Performing security verification

This website uses a security service to protect against malicious bots. This page is displayed while the website verifies you are not a bot."

I click "verify you are human" and it just loops back to the very same challenge. It isn't broken in other web browsers like Vivaldi for Linux. Or Firefox in Windows 11. Just Firefox for Linux.

It has been this way for months.

Whenever I launch a YouTube video, It starts then the whole page freezes. No links work and no menus shows up when I click my mouse. I can do nothing to get the video to unfreeze. All I ca do is close the window.

YouTube is playing 4K videos like they are in slow motion. If I lower the quality they work fine, but switch back to 4K and it's slow motion stutter-fest again. I have seen several topics about this but it's still happening to me despite all of the "fixes" I've tried. This is a list of everything that I've seen and tried, and not a single one or any combination of them fixes the problem for me.

In about:config I tried changed the following to False: gfx.webrender.layer-compositor media.av1.enabled media.wmf.dxva.d3d11.enabled

Tried uninstalling all extensions.

Tried a complete uninstall and reinstall of 149.0.2 with a fresh profile instead of updating from 148.0.2.

Tried installing uBlock Origin and used the following rule: ||www.youtube.com/web-reports$xhr

Tried unchecking the uBlock "Quick Fixes" filter.

Tried disabling hardware acceleration.

Tried disabling DNS Over HTTPS.

All that said... what DID fix it was reverting back to Firefox 148.0.2. I tried again to update from that to 149.0.2 using the FF built in updater but the same issue immediately came back. Zero issues at all playing 4K YouTube videos on FF 148.0.2 or the latest versions of Chrome and Edge. Issue is ONLY on FF 149 and 149.0.2.
