When I click the download button I usually see my recent downloads and click open the file directly from the drop down. After 10-20 downloads are performed the drop down no longer shows my recent files until I restart firefox. I think the issue is once you hit a certain amount of downloads the preview drop down no longer works. Is this a know bug? Its happening on any pc, im on version 104.0.2 (64-bit)

I have used Firefox for my online banking for years. Just recently when I go to the bill payment section and click on the drop down list to pay and view a bill, I can pay the bill, but when I try to view the bill the view bill window comes up for a second and the a drop down of the bank's home page comes up. The view bill page used to be a PDF file and Adobe Reader is my default. I talked with the bank and they did not see it happen in my account. If I open the online banking in Microsoft Edge it does not occur.

I've been using Firefox for several years, and this has never happened before. This is a pretty strange problem and I'm having trouble describing it, so please bear with me.

Since a day or two ago, I've been experiencing a problem where a small number of videos play, but once they get to right before the end, it'll abruptly stop. The play button looks as though the video is still playing even though it's really not, and clicking the play button does nothing. The only way to get the video to play again is to either refresh the page, move the progress bar back to a previous part of the video, or go all the way to the end of the video, in which case it'll allow me to replay it. The videos this problem happens on are completely random, but the problem persists on the same exact videos. This happens with both direct links to videos (i.e. videos like this one) and "embedded" videos (like videos on Reddit, TikTok, YouTube, etc). However, this only happens if the video has no sound or the sound is off, whether I've muted the tab or turned the sound off on the video directly. It also doesn't matter if the video is looped.

There's also a slightly different variation of this issue that seems to happen less often. With this problem, videos will stop right before the end like the videos that have the other problem, but only for a few seconds - after that, the video will end like normal and I can replay it.

I've tried restarting my computer, playing the problematic videos in a private window, disabling all of my extensions, using Troubleshoot Mode, refreshing Firefox, and even uninstalling and reinstalling Firefox. This problem does NOT happen on Microsoft Edge. I'm 99% sure it's because of the new update (105.0), as this issue has only started happening after I updated to it. I updated to 105.0.1 earlier today, and it's still happening. I'm thinking of going back to 104.0.2 if this glitch doesn't get fixed (or at least I don't get help) soon, because I know this issue will seriously get annoying after a while.

Two of the videos that have this problem are this video and this video. Note that both have the secondary version of this problem. I would have uploaded a video of the problem to this post, but this website doesn't let me, so I attached the best screenshot I could take instead.

Any help would be appreciated!

Hello, I am a bit concerned, as Firefox never before acted this way. Has this been reported? 0. Few weeks ago computer froze, after restart, bookmarks that I had made new had disappeared and old ones appeared, as if firefox reversed to previous saved setting from hour before freezing of computer.

Now, the main ones that have been happening during last week: 1. Firefox randomly downloaded (twice during last week) some random file with random letters, for example " H3jO5Ni4m.htm". It was always one file, that was a ".htm" file, and it had 0 bites. I uploaded the file to virustotal and it brought me to this: https://www.virustotal.com/gui/file/e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855/detection

I then googled about this specific problem with Firefox downloading a 0 byte .htm file, and it has been happening to people for last 6 months, not many cases, but some,still. Peoples comments implied that this is harmless and that it is a bug of Firefox.

2. Firefox today,about half an hour ago logged me out of most websites, not all, but most. Firefox never ever behaved this way and it happens only to Firefox, not any other browser that I own.

During last week I scanned my computer in both normal and safe mode with: Eset Online Scanner (a one time useantivirus program), Avast, Roguekiller, Malwarebytes, Mbar (Malwarebytes anti malware), and never found anything. I consider these programs most reliable, and have been using them for years.

Is it a bug of this specific version of Firefox please? I have version 105.0.1 (64-bit) and problem 1 and 2 happened since then I think.

Webpages with divs and buttons that hover a consistent space of the screen like taskbars and Reddit's "back to top" button flicker white and jitter around when I try to scroll and I would like to find a quick fix if possible. I am a new user and I've only so far had to touch config settings to fix on hover UI with Twitter. Everything else is default settings and I keep getting forwarded to old bug reports and github pages for web developers when I'm trying to fix it from the user side on multiple common pages like Tumblr and StackOverflow.

Hello, ever since we moved endpoints from Firefox ESR 91.13 to 102.3, it has become impossible to play any media with Firefox.

No video will play in youtube, for instance (it just loads endlessly as if it would start, but it doesn't).

Can't use radio websites either. Anything with a "play" button (video or sound) does nothing.

This has been tested with a clean profile, a clean install, after allowing autoplay in the settings.

Is there any info on what exactly changed between ESR 91 and 102 that might explain this ? There has been no system change, If I reinstall 91 instead it works again as usual.

No issues anywhere else on the endpoints (Edge, Windows), this is on Windows 10 if it makes any difference.

Tanks for any help on this.

When I click to open a dropdown, it opens and then immediately shuts back up again. I have to maintain pressure on the left click to keep the box open. Any ideas?

Firefox V105.0 64bit Win10 Pro - when streaming Audio, data download is too slow. The Player eventually catches up with the downloaded data and simply Quits when there is none left. This has never been a problem before until this last update . . . . I have tried with Avast's Secure Browser and with MS Edge Browser and BOTH these stream WELL AHEAD of playback - so the problem doesn't arise . . . . With these two Browsers playing an 8 minute .mp3, by the time the player has reached 5 minutes, ALL the remaining data has been downloaded . . . . I made a video from the screen (Bandicam) but the <add images> doesn't allow it . . . . Any Ideas? Or perhaps I wait for the next update and hope it gets fixed . . . . ATB Chris

How to BLOCK systemtimezone detection in Firefox? Can this be done with firefox or with the operatingsystem itself? After all i know for a fact that the bromite android browser has this feature and it works. I noticed that disabling javascript blocks systemtimedetection, but it also basically renders the browsers useless for my purposes.. are there specific javascript config settings regarding systemtimezone detection? I really feel that when a website spys on my systemtimezone this is a breach of privacy as this goes beyond the browsers im using to view the website but instead directly access information about my system, im not ok with that... Using a virtualmachine just to fake systemtimezone cannot be the solution, this is ridiculous.

By the way, i hope Mozilla won't let down support for Manivest v2 ever, there is a chance firefox will gain a boost in users after google pushing Manivest v3 that hard... making adblock useless, what a shame.

I'm trying to download Firefox, but it simply refuses to open. I've only gotten it to open twice, when I downloaded it from the Microsoft Store (which still doesn't work unless I've absolutely cleared my computer of any trace of the Firefox I download from there), but when I tried to open it back up again after turning my laptop off/putting it to sleep, it didn't open.

  I install it from this website otherwise.  I'm on Windows 10 with a laptop, and I've already checked that my storage isn't the issue (I've had it bug apps out on me one too many times).  I've uninstalled everything my computer would tell me exists in relation to Firefox before reinstalling it, but it still doesn't open.
  And when I say it doesn't open, I don't mean it loads slowly or doesn't pull any website up.  I mean for half a second, I see the outline of a window (sometimes windowed, sometimes not, usually with the minimize, windowed, and x on it but not 100% of the time), occasionally a black inside, before it's gone.  I check my running apps and it's not there.  I've tried running it as Admin, making it my default browser, trying to find if there's a 'fix' option for it (as far as I'm tracking, there isn't), running compatibility troubleshooting, restarting my computer, refreshing when it asks me to try, reinstalling when that doesn't work, and properly more I'm forgetting about.
  I really like Firefox, genuinely, I do, I used to use it on an old computer, but I can't open it and therefore can't use it.
  When I opened it off the Microsoft Store, I did sync my Chrome information to it, but I believe I deleted that (I may be mistaken, though), and even if that did pose a problem it still didn't work when I originally tried to download it off of here.  Sorry for the long(?) question, I'm just trying to cover every detail I can think to cover.
  (Warning, I'm a little bad with following detailed instructions, so if any help could be simplified if possible that would help me a lot, thank you for any help anyone can provide!)

I have just updated to the latest version of Firefox on my 3 dell systems to version 105.0.1. When I click on the firefox desktop shortcut I get the error message on the attachment. All 3 were working fine before the update and after the update the systems keeps on getting this message on opening Firefox. I have tried refreshing firefox and all the usual troubleshooting but nothing works. Any ideas please ?

I vaguely remember something about installing Chrome extensions in Firefox. I found a Chrome extension that I'd like to install? Exactly how do you do it? (I can't find anything in Firefox Help.)

Thanks.

Whenever i restart Firefox, my download history gets deleted, but the downloaded files in the file manager don't. I have tried creating new profiles and altering my settings, nothing really works, its the same for all the files, and for all the new profiles i create too. Is there a permanent solution?

I have been using sync from day one: best thing ever regarding my productivity. AFAIK, credentials get encrypted before sent to the FF cloud, using information derived from my password.

Short version: what happens when I change the Firefox account password?

Long version: I'm thinking of replacing my current password, with a very long one. If I do so, will there a re-upload of my data take place? Will my credentials on the cloud become harder to crack (assume that the new password is longer and more complex).

Hi folks,

Forced to update (expected) and 102 ran like two flat tires and no spare whil eI had no issues with 91. MANY hours of searching got me reasonably successful in acceptable performance. But two problems, one which could easily be a bug:

1. I can find no way including in about:config to enable lazy tab loading. In other words, open a group but not load each tab until it is clicked on.

Where did that go?

2. This one is more unique. I have a desktop install of ESR and a portable ESR install on a thumb drive. For MANY years I backed up bookmarks on my desktop and restored them to FF on my thumb drive. Now, after I shut down the portable (which takes a very long time) there are multiple bookmarks. Html files that seem to merge on shutdown. Problem is, on the thumb drive this is not completed before FF shutdown and the processes closed. Results in damaged bookmark files and a crash EVERY time.

IF I drag the copy of FF ESR portable to my desktop and perform the same procedure, no problems. So somehow on a USB 3 thumb drive the process of merging bookmarks. Html files is too slow and will cause a crash consistently.

Any suggestions or should I file a bug report?

Hi amazing FF folks,

FFv105 crashes on web.whatsapp.com Did work on previous version v103 and v104.2

Hope it is an easy fix. Thx a million :)

I want to install a copy of the current version of Firefox on a Win 10 computer that already has an ESR copy of Firefox running on it, without overwriting any of the existing Firefox configurations, that can be run independently of the first install.

How do I do this?
