When I open `about:preferences` tab, `Downloads` directory is created in my home directory, despite my downloads directory is different. I've read issue 474718 which states that it was fix but i still experience it. Linux x86_64

WebGL has stopped working. I think this has happened with Firefox 91.

For example, http://webglsamples.org/aquarium/aquarium.html gives the error Status: WebGL creation failed: * tryNativeGL () * Exhausted GL driver options. (FEATURE_FAILURE_WEBGL_EXHAUSTED_DRIVERS)

I'm running Firefox on Debian on ChromeOS.

On about:support, WebGL 1 Driver Renderer: Red Hat -- virgl WebGL 2 Driver Rendered: Red Hat -- virgl

There are no WebGL errors in about:support

I've tried the Troubleshoot Mode but that made no difference.

I tried signing into google, but when I type in my gmail address and click next, nothing happens. I tried with chrome and it worked. I cleared my cookies and cache, updated and reinstalled firefox and the problem persists. This first happened around a week ago. I use arco linux with xfce. Thanks

When I want to drag and drop a tab into a folder of the bookmark toolbars, I can't do it for some folders.

Specifically, it doesn't work for folders that are somewhat in the area of the tab preview animation that pops up when I start dragging the tab. So that is not the same folders every time, it depends on the tab location in the tab bar.

I hope that the explanation was clear enough, I did a screen record also, made it available here https://ufile.io/pikit6xo (335 kB).

Do someone had a similar issue and found a solution?

I'm in troubleshooting mode. Firefox 100, just updated, but bug was there before. Ubuntu 20.04 LTS

When I try to go to a page that uses Capcha to verify my browser it doesn't display, It will in TOR, Chromium, just not firefox. Now, I can't reach 90% of the sites I usually go to (DICE, Glassdoor, etc. Current version & Things: Application Basics

I'm using Firefox 106.0.1 on Ubuntu 22.10 from Mozilla's official PPA but when I open some websites the browser crashes with the message "Exiting due to channel error.". I found the error could be related to libwebp with LTO enabled, may be it is, but I rebuilt the Ubuntu's package without LTO and one website stopped crashing, dell.com support page, but several others still crash, like amd.com.

I have recently updated to Firefox 106 on two Arch Linux systems. One of them has Firefox View enabled and working by default, another does not. I looked around and tried some options in about:config to enable it, however it did not work and I reverted the changes. I would like to enable Firefox View on this browser as well, and I would like to know how to enable it.

I installed firefox as a flatpak on ubuntu 22.10(kinetic kudu) and everything works fine except for one thing,that being the fact that i cant seem to drag bookmarks from one folder to another, as as soon as the bookmark is dragged from the folder towards another dropdown menu the entire bookmark dropdown closses. as soon as that happens i also cant seem to type inside of firefox restarting firefox fixes the latter issue but not the former.

i hope i explained the problem well

I try to set up Firefox Sync on Firefox on a VM on Fedora. I enter my e-mail and password. Then I get the message (after retrying): "Email resent. Add accounts@firefox.com to your contacts to ensure a smooth delivery." However, I do not get the email with the confirmation code.

My email address has this format j@xxxxx.org

I have a new installation of Ubuntu 22.04 on my 2015 Lenovo IdeaPad 300. I have a new SSD HD 1 TB in size and it should work, however, Firefox keeps crashing. Other apps are crashing too.

Today when I closed Firefox and reopened it the option to restore previous session was not shown, as a result I have lost half my pinned tabs (I managed to redo the rest from bookmarks) which were vital. I tried going into history but the option was greyed out.

This happened yesterday too but after redoing half my tabs I went to open gmail and it restored all my tabs, I tried the sane today but it failed so am stuck with half my tabs.

Please do not suggest I use synch as I only use one device.

After upgrading firefox to the latest version 94.0, it became impossible to copy entrys directly from keepass to firefox. Now to copy entrys, you first need to copy it from keepass to notepad, and then from notepad to firefox. What is the reason for this?

My system is mint 19 and keepass version 2.45

This morning there was an Ubuntu software update and afterwards Firefox wouldn't work, it just opened and hung without ever connecting to a website. So I uninstalled, purged and reinstalled from Ubuntu Software and everything seemed ok. However, whenever I now try to save something, for instance images, the save to directory will default to /run/user/1000/docs even though I have my downloads folder selected in settings. I can change to the directory I want to save to and it will save there, but when I next save something it will again want to go to the /run/user/1000/docs folder. Further, I find that a copy of anything I save has also been saved into that folder, creating a new sub-directory to do so. I tried clear data in settings but that didn't delete those files and they are protected in file manager so I can't delete them myself. This will fill my hard drive pretty quickly as well as being really annoying having to change the save directory every time. What can I do to rectify this? I've now got version 96.0 (64 bit) installed.

Firefox is having issues opening files in my tempdir directory. Opening a file directly, via File -> Open, there are no problems. But, when using either drag-and-drop or when trying to open an attached file from Thunderbird I will get something like the following:

File not found

Firefox can’t find the file at /tmp/pid-15374/etfExpectations_2022-04-22.pdf.

   Check the file name for capitalization or other typing errors.
   Check to see if the file was moved, renamed or deleted.

I work on kubuntu 20.04 with plasma 5.18.8 desktop environment. I have a QtCurve-based custom application style, which I almost match with css for GTK apps. Firefox has to be an exception by itself! Not only that, but it changes my ability to customize its interface, from time to time and even changes access to such ability, on some updates.

My scrollbar customizations in userChrome.css and userContent.css do not work any more (other CSS changes still work, for menu/addressbar/tabbar/bookmarksbar orderint and tab styling). I had to resort to settings in user.js file, to get a 20px width scrollbar, suitable for my big screen, but... it gets very wide when I increase the focus, on some webpages and becomes very ugly! Furthermore, I cannot make sense of the proper use of "ui.themedScrollbar*" settings and the scrollbar and its slider result in the same color. These are my settings in user.js:

user_pref("widget.content.gtk-theme-override", "backwater"); user_pref("widget.non-native-theme.enabled", false); // Use GTK-3.0 gtk.css: set to false user_pref("toolkit.legacyUserProfileCustomizations.stylesheets", true); // Use userChrome.css & userContent.css: set to true user_pref("widget.gtk.alt-theme.scrollbar_active", true); user_pref("widget.non-native-theme.scrollbar.size.override", 20); // If nothing else works, fix scrollbar width to 20px user_pref("widget.non-native-theme.gtk.scrollbar.round-thumb", false); user_pref("widget.non-native-theme.gtk.scrollbar.thumb-size", 1.0); // originally 0.75 user_pref("widget.non-native-theme.gtk.scrollbar.allow-buttons", true); // it was true, anyway... user_pref("layout.css.cached-scrollbar-styles.enabled", false); user_pref("layout.css.color-mix.enabled", true); user_pref("widget.non-native-theme.scrollbar.style", 4); // wide scrollbar theme: set to 4 user_pref("ui.themedScrollbar", "#bad1f5"); user_pref("ui.themedScrollbarInactive", "#668cc4"); user_pref("ui.themedScrollbarThumb", "#e4e4e4"); user_pref("ui.themedScrollbarThumbHover", "#e4e4e4"); user_pref("ui.themedScrollbarThumbActive", "#668cc4"); user_pref("ui.themedScrollbarThumbInactive", "#bad1f5"); user_pref("browser.dom.window.dump.enabled", false); user_pref("extensions.ui.sitepermission.hidden", false); user_pref("fission.experiment.max-origins.qualified", true);

Either with the "ui.themedScrollbar*" settings or without them (and cleared from the prefs.js file), the scrollbar and its slider result in the same color, unless I (tryingly) click on some place on the scrollbar outside its slider; then I can see the slider, _only_ for the duration of the mouse-down event (which causes up or down page-hight scrolling).

The default, very thin scrollbar, as well as my modified wide scrollbar with invisible slider are both useless to me! I have even tried fx-autoconfig (https://github.com/MrOtherGuy/fx-autoconfig) to make the scrollbar CSS work, but no result. At this point, I am considering switching to another browser, despite the trust I have to mozilla, for my data and privacy.

Hello, I've used AddBlock successfully for years but now , to my utter dismay, It has stopped functioning. I tried unsuccessfully to reset Firefox . Have just gone through the latest StartPage privacy protocol added to Firefox, but I am still beset with beastly adds. Hope you can help, Cordially, Joy

I have installed two dictionaries, "English (United Kingdom)", and "French". However, when I go to check a spelling, (right click/Languages over the suspect word), I am offered a third dictionary choice, "English (United States), which I do not want. I have removed the US dictionary and even the language pack but the menu item persists. I can find no way to get rid of it.

Please advise

There is no userChrome.css in my profile.

If it needs to be created, where do I create it?

Yes, I searched for help. What I found was about userChrome.css to solve specific problems, but not what to do if it doesn't exist. Is userChrome still supported?

Thank you! Mark.

On this page with an Atari emulator, I am unable to use its controls that use the Alt key, such as Alt+P to pause.

It works with another browser, or with a fresh profile.

I've tried disabling add-ons and trying it again, but it fails even after disabling each of them. It also doesn't even work in troubleshooting mode, and that seems kinda odd?

It may be some modified settings in my Firefox profile? Though if it is, I don't know what settings, nor how to fix it. What sorts of settings are retained even in troubleshooting mode?
