Firefox supportforum

No longer able to copy or paste text on Firefox with Windows 10. Copy and Paste are greyed out in the right click menu after selecting text. Using CTRL-C, V or P does nothing at all. Still works fine in other browsers. What has Firefox broken again this time?

For the past two months, my Firefox Linux keeps crashing. I don't know why.

Here's the text from the Mozilla Crash Reporter window that pops up after Fox crashes: Accessibility: Active AdapterDeviceID: 0x5917 AdapterDriverVendor: mesa/iris AdapterDriverVersion: 23.0.4.0 AdapterVendorID: 0x8086 Add-ons: langpack-en-GB%40firefox.mozilla.org:121.0.20231211.174248,langpack-en-CA%40firefox.mozilla.org:121.0.20231211.174248,uBlock0%40raymondhill.net:1.54.0,treestyletab%40piro.sakura.ne.jp:3.9.19,%40contain-facebook:2.3.11,addon%40darkreader.org:4.9.73,%7B7a7a4a92-a2a0-41d1-9fd7-1e92480d612d%7D:1.5.41,%40testpilot-containers:8.1.3,magnolia%4012.34:3.4.5.0,%7Ba6c4a591-f1b2-4f03-b3ff-767e5bedf4e7%7D:0.5.0,formautofill%40mozilla.org:1.0.1,pictureinpicture%40mozilla.org:1.0.0,screenshots%40mozilla.org:39.0.1,webcompat%40mozilla.org:121.0.0,addons-search-detection%40mozilla.com:2.0.0,google%40search.mozilla.org:1.4,wikipedia%40search.mozilla.org:1.3,bing%40search.mozilla.org:1.6,ddg%40search.mozilla.org:1.4,ebay%40search.mozilla.org:1.4,firefox-compact-dark%40mozilla.org:1.2,amazondotcom%40search.mozilla.org:1.7 AvailablePageFile: 0 AvailablePhysicalMemory: 824360960 AvailableSwapMemory: 2147479552 AvailableVirtualMemory: 9762406400 BackgroundTaskMode: 0 BuildID: 20231211174248 ContentSandboxCapabilities: 119 ContentSandboxCapable: 1 ContentSandboxLevel: 4 CrashTime: 1703535161 DOMFissionEnabled: 1 DOMIPCEnabled: 1 DesktopEnvironment: x-cinnamon EMCheckCompatibility: true ExperimentalFeatures: network.cookie.sameSite.noneRequiresSecure,layout.css.grid-template-masonry-value.enabled,devtools.inspector.compatibility.enabled GpuSandboxLevel: 0 GraphicsNumActiveRenderers: 4 GraphicsNumRenderers: 5 HeadlessMode: 0 InstallTime: 1703210473 IsWayland: 0 LastStartupWasCrash: 0 LinuxUnderMemoryPressure: 0 Notes: Linux Mint 21.2FP(D00-L1000-W0000000-T010) WR?

Hi all,

I feel like this is a problem that must have been experienced and solved a thousand times... however I've tried all the suggested fixes I can find and the problem still persists.

When I load Firefox the pages take ages to load. It doesn't matter what the page is, it takes ages, except that about: pages load fine, no problem. When I say pages take ages to load, I mean that everything about the page takes ages, not only the next, not on the images and other content etc, everything. This only started happening today and I only created a new profile a month or so ago. I don't have many tabs open (maybe 20) of which 9 are pinned. I do have lots of extensions installed.

I've tried troubleshooting/safe mode, that makes no difference.

Private browsing and loading another profile are fine, they don't have this problem.

I've cleared all cache and data, cookies, etc, including startup cache.

I've deleted the content-prefs file, and removed places files.

I've tried disabling and enabling hardware acceleration.

I've tried disabling TRR.

Probably some other things too, but so far nothing has worked.

Suggestions please! :)

Starting this morning I suddenly cant delete or mark emails as read in Outlook.live.com. Even if I open an email, and it appears as read after that, if I refresh or leave the page and come back, its marked as read again.

I tried dropping all add-ons (a kill switch to drop all add-ons and re-activate them is still a feature I feel Firefox needs, I have to click every single one of them every time) to no avail.

I was in the process of writing this question on the Microsoft forums (which is usually like whizzing in the wind) when I thought to try a different browser. I had zero issues and Outlook.live.com worked perfectly normal on Microsoft Edge.

This HAS to be a bug in a recent update in Firefox

I searched Microsoft forum and opened the first link (https://answers.microsoft.com/en-us). On Firefox, Go back one page (back arrow) button was not working on this website.

I need step by step on how to recover deleleted passwords

please do not respond unless you are going to tell me step on step what i need to do with loginbackupjson

Exported a bookmarks html file from Mac (Sonoma OS) and tried to import it in a computer running Zorin (linux) 17. The file can be found, but when I click it, I am told there are no bookmarks therein. If I open the HTML file it's all there. Full of bookmarks. What am I doing wrong? Thanks for reading.

I have been using FF for many years but recently have started having issues on eBay.co.uk

At the moment it specifically relates to leaving feedback on my sold items.

I'm currently logging in on MS Edge or Chrome to leave feedback as FF just will not work.

I've tried FF on a clean install on a 2nd PC (no add-ons) and still get the issue.

Please help as I am now having to use Edge & Chrome so much I may as well move over to them which I would rather not do.

I'm a long time FF user. Version 121 works perfectly .

 Ever since 121.01 , updating breaks EVERYTHING.   Most of my add ons cant access their data, websites dont work, etc.  

 Not only that ,  but reverting to 121 does not help.   So the profile data itself is being trashed. 

 Restoring the full profile from a backup is successful, but only with version 121.   Any version beyond that breaks it. 

 I also tried a full delete and reinstall of Firefox, but that did not work.  Same problem.

 A full rebuild of all the add ons from scratch  might be my only option at this point if we cant figure out why this is happening.

Had it yesterday, happened this morning after the restart and just NOW, when I entered 6 lousy tabs, and they are NOT in the recently closed list either.. wups, gone, no tabs, setting has a check mark on open previous windows and tabs. Within 24 hours, lost the tabs three times with a non reported crash and Firefox closing itself with no warning.

I honestly do not think I am responsible to keep a backup of my browser history, I expect a browser to do that. I switched from Opera to Firefox not to long ago.. even Opera is a security risk.. at least it doesn't delete your tabs just for fun.

Very simple.. that happens once more and i am OFF this browser....

TO MOZILLA DEVELOPERS

In spite of hundreds if not thousands of users reporting this issue over and over again, and your suggested workaround to reduce memory usage in the settings that doesn't do anything - FIREFOX is still using unacceptably HUGE amount of memory.

With just FOUR (4) tabs open in one window, in the Task Manager I can see 17 (!!!!!!) Firefox windows open using 830 MB of memory. The highest usage of all my apps including memory hungry media apps. It's using THREE times as much memory as my Adobe Audition processing edits of a 1.5 hr audio with several clips.

This is insane!! You have gone crazy with caching to the point of making this browser unusable.

It's freezing up and crashing my Audition so before I work in it I must shut Firefox down completely - and I work on a powerful tower PC designed for media.

If you don't seriously cut back on this insane caching for the sake of browsing speed IN THE NEXT UPDATE, I won't be using your browser at all, it's simple as that. I'm already migrating my bookmarks and setting up Chrome which uses about half the memory that Firefox does with the same tabs, and I suspect that many users will follow suit.

The workarounds you offer DO NOT WORK. Any app that uses more than 500 MB of memory at any give time on my computer - goes.

Over the past few weeks I've been unable to watch live videos on Firefox on Ubuntu 22.04. I thought it was just an issue with Twitch but I realized the problem also persists on live videos on Youtube and did some troubleshooting which didn't solve the issue. The only solution I was able to find for Ubuntu said to install ffmpeg, which I already had, but I made sure it was upgraded, refreshed Firefox, and still have the issue. Currently I'm on Firefox 121.0 but I've had this issue since before I updated it. I dual boot Ubuntu and Windows and am not having this issue when I boot Windows on the same computer and Firefox profile.

I know this is an ongoing issue but it seems like nobody has mentioned it in a while so I figured I would stir it up again. I am fed up with the bookmark double spacing and having to scroll down all of the time.

If nothing else I would think that the Firefox team owes all of its loyal users an explanation as to why they don't seem to want to fix this probem.

Thanks my rant for this year :)

Firefox for Linux has a bug where it is unable to drag a tab from a non-active window. As in, if the window focus is on Firefox window A and I try to drag a tab from Firefox window B to window A, I have to click first the window. I can't just intuitively drag the tab from a non-active window, because it will get ignored. It will just activate the window, ignoring the drag.

Hello

I got a new Asus Vivobook Core i9 16G Ram I did the basic Windows 11 installation for the Laptop and installed TotalAV.

After all Windows 11 updates passed, I wanted to install FireFox anf got this issue: Firefox cannot start correctly (0xc0000022) after version ..

I tried several time to close all Firefox task, uninstall, remove all files from existing profiles (local, roaming, etc...) so as all files under "Programs"". I made sure to get the latest code, but I always get back to this issue.

While opening FireFox, I immediatly get a Crashed Tab reported. Even the Settings are not opening in a Tab.

I even tried to use a older version. Same issue... Never the less I can Update the older version in "About FireFox".

After update I see 122 installed

I used FireFox for many years, and wanted to continue.. In the meantime I installed Opera

Any help is appreciated. Thank you in advance Laurent

Hey there! After updating Firefox to 121.0.1 YouTube latest videos box not showing. It appears for a few seconds after page is loaded, but then just disappears. Checked on another computer -- the same issue, although in 120.0.1 works fine.

With 'Back up your Firefox data' it says it saves all open tabs.

What is meant by 'open' tabs? Is it tabs that I have clicked on during my session?

I have just over 300 tabs, will Firefox save all of those tabs in the cloud or only the tabs I clicked on during a session?

When I right click on an image and select "save as", after selecting where to save it and then selecting save, firefox just hangs and is completely unresponsive, leaving me having to terminate it through task manager. No error message ever come up, Firefox just freezes.
