"The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can caused this problem".

How do I resolve this problem?

Youtube just does not run well on the firefox browser, I have had this issue on my pc, as well as my laptop. Twitch, piracy streaming sites, 9anime all work fine this problem with loading and buffering is exclusive to youtube. I have tried resetting my firefox settings, changing the values for load times and resource usage in about:config and none of these have fixed my youtube.I have tried multiple fixes I've been recommenced by online forms. I have switched my user agent to make youtube think I am using chrome, I have disabled and removed all of my extensions including ublock origin, and loading youtube remains painfully slow. In fact, disabling adblock makes the load times even slower.

Also responding to my post with "hmmm durrr it works just fine for me" does not help anybody, stfu.

I have sound in Windows, but YouTube is dead quit. I have tried all that is suggested in Firefox help and some YouTube sites. Nothing worked. I have tried off the computer and restarted, but no change. My system is Windows 11, sound works, and the latest Firefox update installed. Question is this a YouTube tacit to stop NoScript and uBlock?

I'm using the vertical tabs feature. I also tried enabling the "Expand sidebar on hover" option, which minimizes the side bar, and only expands it when you hover on it.

Issue: I have a lot of open tabs, and I'm usually working with the ones at the bottom of the list. When the bar minimizes the scroll position resets back to the beginning. So, every time I want to select a tab, I have to scroll back down, which makes this feature very hard to use.

Expected behavior: After the vertical bar minimizes, and I hover again, it should keep the scroll position.

So i use garuda linux(not sure if necessary but still telling). The ".mozilla" folder is about 134 GB! I have browsed it a bit and found a lot of this folders "vuzpdtyn.default-release-backup-crashrecovery", "tor50voj.default-backup-crashrecovery-", "profile-somestuff-backup-crashrecovery" Is it safe to delete the old ones from this?

So, today i opened up my firefox and loaded up youtube; it didn't load. I tried to check my wifi speed on speedtest by ookla...the website didnt work. Then i went to reddit to see if this was a bug affecting everyone anddd that also did not work. So, basically half of the websites that i use do not work right now and i can't figure out why. Everything was fine till yestderday and i havent changed any settings. Also, Wifi speed is not the problem here as i opened up ms edge and everything works.

Please help! Here's a reference image of how websites look ( imgur ) Funnily enough, imgur also did not work of mozilla.

Recently, I have not been able to upload a video to YouTube. When I try to upload it, the upload is stuck on 0%. I tried another browser, and it worked fine. This has not been a problem until. I have uploaded many videos. The last time was about a month ago. So, maybe there is some problem with an update. Does anyone else have this problem or know the solution?

Yesterday I have updated tp macOS 15. Sine then I have trupuble displaying any webpages in Firefox 130. Th econnection just times out. Any other browser such as Brave, Safari, Home, Edge are still working as before teh update. How to fix this please?

Hello, I'm having an issue with how Firefox is displaying images on some of our product pages. The image appears to be zoomed in which cuts off the side of the product image. The exact same product page displays completely fine when using Safari and Chrome. I cannot figure out the issue. Please see attached images.

I have tried:

modifying the about:config page prefs:

   browser.enable_automatic_image_resizing
   browser.enable_click_image_resizing 

I have also tried resetting the zoom features (Command/Conrl +/-/0).

I have also tried reinstalling firefox and running the browser without any extensions.

None of these worked. Any suggestions?

My Firefox browser is updated to the most recent version. I've previously used ProtonVPN and I've never had any problems. As soon as I updated Firefox, however; there are connectivity issues and pages won't load. I've tested with other web browsers and are able to load pages there while they simultaneously won't load in Firefox. I've tried deleting ProtonVPN and re-installing, but that didn't work either. I reached out to Proton about this and they are looking into it from their end to see if there is a solution, but I'm pretty confident it has something to do with Firefox as other browsers are working as they should be.

Hello, when i fullscreen video on youtube video stops buffering. When i end fullscreen buffering immediatly starts and everything is okay. Back and forth. I tried: reinstall to lastest mozilla release, disable addons, stoubleshoot mode, increase cache in about:config and other public solutions i can google. When i look on "Statistic for experts" on youtube there are three bars and it shows: Normal size player: Connection Speed - some amount of kbps (works) Network Activity - some amount of KB (works) Buffer Health - some amout of s (works) Fullscreen: Connection Speed - some amount of kbps (works) Network Activity - 0 KB (doesn´t work) Buffer Health - 0 s (doesn´t work)

I cannot use Firefox or Thunderbird I keep getting an error code: PR_CONNECT_RESET_ERROR The problem started straight after the latest update a few days ago.

I have cleared the cache and cookies I turned off the addons and extensions I shut down the internet security I changed the proxy settings to "no proxy" I even changed cert9 to ccert9 and had firefox generate a new cert9

Nothing has worked.

HELP!

Just a few days ago, screenshot technique failed. I often copy an image from webpage. Right click technique. I am still able to do this. I have option of copy or Download. Download works but Copy does not. When I try to paste the copy into my Word document, I get a blank image (a square that indicates there was an image but the actual image is not there). How can I get the paste mechanism working again?

There's one specific field I fill in very often and for some reason Firefox is really keen on suggesting me two searches that I looked up more than a couple months ago, on a totally different site. I can't even remove these suggestions or add new ones. When I used Vivaldi, it'd learn what I insert (even if it'd end up suggesting tens and tens of options), while Firefox doesn't learn at all.

For sake of an example, let's say that the word I use every day in this field is XYZ. Not even once was it suggested to me, I've only ever gotten the two in the screenshot below instead. And I can't remove them using the Delete key as some other article suggested.

Speaking of which, I just noticed the same thing happen to the subject line in this form 🙃

My Firefox now only opens to a partial page size, not full, even though I click to a full page and then close out.

Opening again just goes to a reduced size page.

I have backed up my profile, uninstalled Firefox and reinstalled and brought my profile back in.

Still the same problem.

I think there is a file that controls this that is corrupted.

Need help.

I have reinstalled Firefox on my Mac many times, completely removed all files using app cleaner, and reset Firefox by holding shift and option on start. Despite this, the app is very slow to launch, and when it does no pages load or render. Opening a new tab freezes the entire app for 15-30 seconds, and when the tab opens it is completely blank. Attempting to browse to a URL does nothing, and the address bar just returns to being empty. Attempting to open settings does nothing, although parts of the app that open separate windows such as the about version info and bookmarks work fine. The only thing I haven't done at this point is completely reinstalling macOS, so maybe there is something wrong with my system config. I first noticed this issue when using the early macOS Sequoia betas, and assumed the app wasn't updated to support it yet. However after updating macOS and completely removing and reinstalling all traces of Firefox, it still doesn't work. I am currently using macOS 15.1 beta, however the issue also persisted on 15.0.

I use Internet Bill Pay through my bank, and it has always worked correctly with Firefox. I have enhanced tracking protection turned off for the site secureinternetbank.com and I have cookies authorized in my exceptions list. Today I got this message:

Why can't I access Bill Pay?

Bank says it hasn't changed anything, and no tweaks I tried on privacy settings fixed it. I believe it's an issue with the new version. Can you tell me how to fix it or let me know when Firefox will fix it? The site works fine in Microsoft Edge, but I'd like to avoid using Edge.

Thanks.
