when close firefox on build 120.0 64 bit build slow to open website after that its fine its only first time opening firefox on windows 10 64 from fresh restart or cold boot or closeing and reopening it dose it hope fixed soon in next build

FireFox 120 unable to update(!) on Win11 Home (recently updated) & my android 13 phone this evening. I'm using Waterfox G6.06 to be able to write to you! ERROR: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT for any site except google mail ?!

First noticed issues when using X.com on my phone (stopped loading even after 2x cold boots) I use FF Beta on it; downloaded FF full for Android & X still don't load. Still can't get FF to update itself. Tried the Installer for Win & no go. Sigh.

I have some .htm files which are stored in the root / directory and I would like to know how to access them in Firefox, running on Xubuntu 22.04 LTS

Interestingly enough, I found a solution here: Firefox Quantum: HTML files from internal (/usr) do not open which did solve my issue on my Virtual Machine which is running the same Xubuntu 22.04, however since performing a clean installation on a physical machine the same solution has not worked and I just get the follow error as shown in my image.

Despite removing the snap version of Firefox and performing the installation shown in this guide: How to install Firefox deb package, my physical machine just cannot access my local .htm files.

This has never been an issue for me on RHEL environments, and the file path syntax I am using is: file:///my_dir/my_dir2/index.htm

The directory permissions are: drwxr-xr-x root root

Firefox crashes almost immediately upon startup. Have run through each step of: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-crashes-closing-or-quitting

and while I wasn't able to get the RAM memory test application to work, none of the other steps worked either.

I have a content filter installed on this computer, that's the only other thing I can think of that is causing the issue. Help would be greatly appreciated.

After the most recent update, Firefox often takes 30 seconds or longer to load pages. This behavior began yesterday and has continued today. This isn't the first time this has happened. Solutions?

macOS 14.1.1 on an M2 with FF 120.

When going to sites such as nbcnews.com/now or https://toronto.ctvnews.ca, A/V sync is off by about a second.

This appears to be due to the volume being muted when video playback starts. Unpausing the video leads to the video freezing for a very brief moment, then the A/V sync is clearly incorrect.

This can be replicated on YouTube by loading a video, muting the video (if not muted already), refreshing the page (F5), allowing the video to play, then unmuting the video. The sync will be incorrect.

If the audio is unmuted when the video play back starts, this does not appear to happen.

Following this article has no impact: https://support.mozilla.org/en-US/kb/performance-settings, nor does setting media.hardware-video-decoding.enabled to false.

This issue does not occur on Microsoft Edge.

So I've scoured the Firefox community help and have done everything: disabled cookie auto-delete, make sure I have "always use private browsing mode" unchecked, make sure Firefox always saves logins/history/etc., have security set to "Standard," and have added exceptions to the Firefox security; yet, despite all this, I'm still getting logged out everytime I close the browser. I'm getting to my wit's end!

What else can be done to fix this? It's really frickin annoying having to sign back into everything, everytime I open Firefox. Thank you in advance.

I am running Firefox on a Windows 10 computer. I have had little-to-no problems with Firefox before now. Since this morning, every time I open Firefox, it almost instantly crashes. Even after refreshing it and reinstalling it a few times, the problem persists. I have no idea what the cause is; I don't remember drastically changing any settings or anything like that. It will crash even when I use safe/troubleshoot mode, when I open a private window, and when I run it as an administrator.

I got to a point where it would give me a sliver of time before crashing. Following the advice of a Firefox help article, I managed to clear all of its stored cache and cookies(if I remember correctly). Still no fix.

If anyone knows how to fix this, I'd love to hear the solution when convenient for you.

Other browsers and programs manage to use the web just fine, but lately, firefox is hanging for minutes at a time, spinning its wheels, when I try to do anything online. It happens multiple times per hour, for several minutes. No idea what is wrong. I tried everything firefox recommends. Nada. Anybuddy have a clue? About to go back to the darkside, chrome. This is maddening.

Just downloaded Firefox and I cannot for the life of me get it to access the web.

For starters, I am on OS Montery 12.7 and I use a hotspot for internet from my iPhone 7 (no other internet available).

I have set Firefox to use no proxy, and there is no proxy in use on the PC. The firewall is also disabled. Tried clearing the history (incl. cache) and still no dice.

I will try using a wifi connection when at uni next week, but I'd like to be able to use this while on hotspot as that is what I use 99% of the time.

Any help is really appreciated! Thanks.
