Firefox Community Forum

Out of nowhere a couple days ago Firefox started loading local html files extremely slowly. I was using Live Server to render the pages, so I turned that on and off, uninstalled and reinstalled to no avail. I tried dragging files in from the original folder on my computer, but even that doesn't work. I tried updating firefox, and then my computer (which is running Fedora Linux 40), but still nothing.

When I try hitting inspect on the page, it only loads the HTML but doesn't let me inspect the JS as it wont load, and it's saying I have a ton of errors too. I can't look at the errors because they wont load, but I know it doesn't have to do with the original file as there was only one error which the page was working fine with before and each time I try opening the file it gives me a different amount of errors.

I tried clearing my cache and cookies, which didn't work either.

Does anyone know how to fix this? I'm having no other errors on other pages.

When using built in search (google default) -- browser stops responding. Shows Firefox new tab background when loading the search. Issue resolves on Firefox close and re-open. Paste and go, creating new tabs also fail with same 'new tab background' displayed. Issue is intermittent but appears often, at least 4-5 times a day.

Tested same sample search with google chrome in same time period, no issue.

Issue appeared around the V99 update. Fix would be greatly appreciated - exiting and re-opening browser, dropping all tabs to reload is a serious usability issue.

For over a month now i have a problem with youtube. It loads videos very badly. I have good connection speed, but 0 network activity and 0 buffer health in Stats For Nerds on youtube and videos dont load. I can wait for 10-15 minutes (but sometimes they load almost instantly) before video load 40 sec buffer and after that buffer ends i can wait for another 10 minutes befor it load buffer again.

This problem persist only in my firefox on my computer. I tried deleting all the extensions, reinstalling firefox, "refresh firefox" future, changing useragent, reinstalling windows (it was the time anyways) but it doesnt solve the problem. I dont have this problem in other browsers (edge, librewolf, chrome) on my computer.

OS: win 11 x64 Firefox 127.0 x64

from 89338383 sites just google sites have this problem. And nothing work. is so annoying ill uninstall firefox and this browser forever. 9/10 times wana go on google or yt Secure conection preblem is making me mad its an firfox account bug not the visited site have problems.

FireFox just updated itself to the latest version (127.0.1 (64 bit)) on my Windows 10 laptop. Now every time I try to close it, instead of closing, it starts a background process and then crashes after about 25 seconds.

I am running Mac Big Sur, 11.7.10. When I am in Firefox version 127.0.2 and I go into any Google search, the tab crashes. It works in private browsing mode and also in other browsers but not in non-private browsing in Firefox. I have tried disabling extensions, add ons, etc. Nothing seems to help. This started happening a few weeks ago with any YouTube page also. How can I fix this? If I can't I will stop using Firefox as I cannot function like this. Please advise!

YouTube has been so slow in Firefox. It just takes a ton of time for the video to actually play. It's just a spinning circle in a video. I can refresh several times and then it plays. I cleared my cache, history, data...etc everything from Firefox. That seemed to help for a bit. Then it just resulted back to being slow. It's just in Firefox. I played videos in Edge. It was fine. No issues. It's just FireFox. It started most recently too. It wasn't happening a week ago. I even tried going back to an old version of Firefox. Didn't help. Anyone know how to fix? Not using ad blockers either FYI. I just want videos to play normally and fast.

Hi, I hit Foxfire icon, I get XUL Runner message,

Error Platform Version 127.0.1 is not compatible with mini version ] = 127.0 and max version ] = 127.0

How do I correct and gain access!!???

Please help, definitely liked days of yore when one could call.

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

I have not been able to connect to www.paperbackswap.com for 2 days using Firefox. I get this message - The page isn’t redirecting properly-An error occurred during a connection to www.paperbackswap.com. This problem can sometimes be caused by disabling or refusing to accept cookies. This is a persistent problem happening every few days. I have sent messages before to PBS and Firefox with no response. I have cleared cookies and added PBS to Firefox as a site to always accept cookies. I can access the site using Chrome but I would prefer Firefox. Is there anything that can be done?

My Firefox has intermittently (but many times a day) been been slow loading, often simply refusing to load at all. Clicking a link to open in a new tab often opens the tab but the tab says "New Tab" with an oscillating dot on the left. After a few minutes the dot stops and nothing displays. Often clicking something in Google News the new tab says "Opening " and then the Google URL. The page sometimes displays after a couple of minutes but sometimes never does.

I've disabled all my plugins except LastPass, but that doesn't help. My IT Support company hasn't been able to help. I tweeted Firefox and they suggested I DM them. I've done that, even sending a couple of illustrative screen videos. But no oikne has ever responded to my Twitter DM.

Is there any way to talk to a live person and share my screen to get some help?

If not, I'll need to abandon Firefox as my default browser after many, many years. It's become a real productivity-killer.

Hello, i used to watch betfair live videos on firefox, but since the last update, some of the videos simply don't work. Was there any changes made to the videos player?

Sadly im forced to use another browser to see the videos.

If u have any info on that problem please let me know.

Thanks

Over the last year I have uninstalled FF removed settings then reinstalled from scratch. Its been over a year now and FF never can pin point where I am at. Today it says I am 1300+ miles from where I am. I really don't want to go back to using Chrome but it appears I will have to as it normally has my exact position. I travel for 6 months of the year and have 3 internet connections shared via an internal WiFi that I use 99% of the time. They are connected via Starlink, GoogleFi (T-Mobile) and AT&T SIMs. I have a SSID with the _nomap suffix and that fixes Chrome but FF NEVER seems to know where I am, no matter how many times I clear the browsing data. I really don't want to go back to Chrome, but I cannot do my work if FF thinks I am somewhere else all the time. Geez, If only there was an addon or extension that would override FF location so I could tell it where I am. I'm in FF Hell. -Bill

In Firefox, after a reboot, how can I re-open my previous sessions?

Originally I had quite a lot of open browsers & tabs. Then I needed to do a reboot, and now I've lost those previous sessions.

Usually I just open Firefox, and this opens one browser, and then all of my previous browser, and tabs reopen, but this time Firefox crashed, and its popup said it needed to restart, but it would re-open my previous browser and tabs, but it didn't.

After following the usual Firefox help guides, it still wouldn't re-open my previous sessions. Now if I ask it to open my previous sessions, it just opens the recent help guides, and not anything before the crash.

So is there a backup file of my missing sessions that I can roll back to?

I tryed Firefox 115.8.0esr and 115.9.0esr 32Bit on Windows 7. (78.15.0 works) Firefox crashes(the whole program, i mean no tab) on "about:support" or some pages on support.mozilla.org like https://support.mozilla.org/de/kb/firefox-leistungseinstellungen always reproduceable.

I disabled all Addons, i disabled this power optimizion setting, removed usercrome.css same. With Firefox savemode it dont crash. Spyware is blocked, means datareporting/telemetry/ping by disabling the options and empty the urls (like on FF 78 but it dont crash). Somewhere i read firefox can crash on a empty url, but i assume its fixed long time ago. A wrong, unreachable or empty url should not crash on well programming. Think about countrys that blocks urls, adblocker, pihole and so on. I dont remember about what url i read.

Does the savemode revert all about:config settings? What does support.mozilla ask the browser that causes the crash? It know it seems to identify the Browser, but usual its done by useragent and no "internal" communication.

Then FF always crash on ebay.de search if you scroll or change settings while the page is not ready. Spyware is too blocked by Hardware, ebay may wait for some ad? But thats already on FF78 but on 115 it seems more often, this was not with FF 52. But some sites including ebay stops to work with FF52/78 so no choice.

I am using Firefox 127 on Ubuntu.

When I press the Control key, I often lose focus in the window I am currently viewing. This is annoying as it prevents me from copy-pasting for example.

Sometimes the focus is back when I release Control, sometimes it is lost and I have to click again on the text field. It does not happen on all websites, for example support.mozilla.org works well, but it happens on duckduckgo or overleaf.

It does not seem to be the same as existing issues such as [the "show mouse when press Ctrl" of Ubuntu] (it is disabled) or an addon (the problem still happens in safe mode).

In case it is useful, when I press Control the tab bar background goes slightly darker, see attached images.

Thanks for your help :) Nicolas

There are sites, including yahoo that all my comments are coming back as "comment failed to publish" or other sites where comment section just not there. Seemed like this started happening after a recent Firefox update. I have contacted web sites, my protection service and they have, after research come back with problem is Firefox. If there' something I've done or not done to have this happen, let me know. It DOES NOT happen when I use, as example Edge or anyone else. Thanks......Mike

I like Firefox and am using it for years, but I cannot accept lengthy loading time. I have a fast and stable internet so this is not the problem. Please let me know what the problem is and how to fix it.

I cannot print from Firefox. It worked fine, and then stopped. I'm not sure what changed. It doesn't matter what printer I use. Even printing to PDF fails. No errors appear, and nothing shows up in the printer queue. All the other applications in Windows print just fine. It's just Firefox. And just for this one Windows user.

I tried clearing the saved printer settings in the about:support page. I tried refreshing Firefox. I tried uninstalling and reinstalling Firefox. I tried uninstalling, removing the mozilla folder in %appdata%, and reinstalling Firefox. No luck.

The only time I can get it to print anything is to log into a different user account on this same PC. Printing from Firefox seems to work then.

It seems there is some user-specific printer setting/file/whatever that is messed up. I'm not sure what else to try.

Thanks.
