As per this issue I reported a while back, I was experiencing odd issue with automatic redirect to HTTPS for some private development sites.

I finally found a fix for the issue. The problem appears to be with DuckDuckGo Privacy Essentials Extension which apparently *may automatically redirect to the http site. In order to prevent this, I added my development sites to 'Unprotected Sites' and this prevented DuckDuckGo from doing the automatic redirect to https.

• - Odd thing is that I had multiple domains pointing to the same web instance and only one of the domains was having this issue with the DDG extension. Both were going to the same IP through a HTTP proxy. The proxy and web server were not the issue. This symptom points to an maybe an issue in Firefox....

In summary, be wary of odd redirects and the DuckDuckGo Privacy Essentials extension if you are doing web development work.

FF updated yesterday with the new Ubuntu 22.04 (Pop) update to 99.01. Since the update the volume control inputs are essentially disabled on all web sites, and they default to max - even when muted.

Example - youtube - all videos play full volume Reddit - even muted videos play full volume

The volume can now only be controlled by the system slider.

The same behavior does not occur in other browsers - e.g. Chromium, Opera, etc.

Can anyone assist?

Hello

I do not understand how firefox sync is supposed to work. I have a desktop and a laptop. The desktop is FF 85 on Linux Mint (I cannot get a later version due to some querk) The laptop is 99 on Windows 10 Both are signed in to sync but my bookmarks were scrambled so I signed out the laptop and cleared the profile, cleaned up the bookmarks in the desktop and to be safe I tried just syncing the tabs, not the bookmarks, by opening the fresh firefox on the laptop and signing in again. In the sidebar under my account icon I clicked "Synchronise now" and the open tabs from my desktop appeared in a list underneath, jumbled up. (I have 2 separate windows open on the desktop with different tabs in each, but this separation was not followed either, there didn’t seem to be any provision for syncing tabs in two separate windows)

But the row of tabs didn’t open, all I can do is open them one by one from the list on the right, this is a slow process as every time I click on a tab in the list the new page opens in the same single tab, not a new one, but the sidebar closes again.

Is this what’s supposed to happen? I was expecting the synced row of tabs to open automatically.

This feature would have been useful as my OS on the desktop, (Linux Mint) tends to crash and to have the on the laptop would be a good backup.

Incidentally the other way I try to back up the lost tabs is to select them all and bookmark them to a new folder which I call “backup” but it seems this doesn’t necessarily duplicate them, which I would prefer, so any of the open tabs that were previously bookmarked risk being removed from the original bookmarked folder, without my noticing, and I am therefore reluctant to delete the backup folder without checking that it doesn’t contain the only bookmark of a page.

When I came back to syncing the bookmarks, how do I avoid them getting scrambled again?

I am developing an extension. I am running the extension locally and I have noticed that it doesn't load on this page (https://support.mozilla.org). Is there some limitation to running extensions here? The same extension works fine in google chrome for this page. It is very important for me that the extension runs everywhere since it's an accessibility extension.

I forgot my password to my Firefox account, and only just realized I haven't updated it in KeypassXC when I was trying to log in to a new machine. It seems that, even though I am already logged in on my old computer and have full access to my account (including saved passwords, bookmarks, and browsing history) I can't find a way to reset my password without deleting all of my synced data. From the "Change Password" menu, it requires my old password if I want to change it without deleting everything. Also, I have 2FA enabled, so why isn't there the option to authenticate my identity in a password reset using 2FA instead of my old password? I know a similar thing already exists for recovery keys, but I only have 2FA. Is there any way for me to reset my password where I don't lose everything? Thank you.

Hi,

I've upgraded to Firefox 99 (on Linux) and a website that works fine in Firefox 88 and Chromium 101 has stopped working for me - I can't get the log in form to show up.

This is in a standard window (as opposed to private) with all add ons disabled, Enhanced Tracking Protection switched off for the site and protection settings set to 'Custom' with everything switched off (and same with protection settings set to 'Standard').

The website is:

https://www.riverford.co.uk/

and then click on person icon in the top right corner.

I'm having similar problems with other websites, eg

https://www.ebi.ac.uk/interpro/

in a private window (but weirdly works fine in a standard window) - click on 'Example protein sequence' to fill in a sample sequence and then press 'Search'. In a standard window this works but in a private window the 'Search' button doesn't work. (If the search button does work for you, please delete the job afterwards by clicking on the rubbish bin/trashcan icon so as not waste their resources.)

I got help with this from your group some weeks ago, but I had to reinstall my Ubuntu OS (linux v.20.04.4 -- using firefox) recently and can't recall the answer.

When I view a WikiSpecies list of file names (e. g., see https://species.wikimedia.org/wiki/Pentatominae), the instances which have been installed but never used should be in a different (reddish) color. I am attaching an image of a page containing a file named "Abadia" (first one on the left, just under "A") which is unused. I also am attaching an empty "Creating Abadia" which is the result of clicking on "Abadia".

Please tell me how to change the image of an unused, empty file. I recall that there were two different choices SOMEWHERE in the system, "Always" and "Never" I think: One of them forces a system-level color pattern which includes reddish unused items; the other allows the used to program arbitrary displays such as the above (typical example from the dconf editor is 'bg_color: #f0f1f2; selected_bg_color: #023C88', but this editor does not change the appearance of a file instance.

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.

I am sending tabs from Firefox mobile to Firefox desktop (Arch Linux) (on a regular base for years). All worked fine. After a new install two weeks ago the Firefox desktop receives the tabs and opens them as supposed. But after a day or three when I open Firefox desktop it opens all previous tabs again together with the newly sent tabs. I deleted the Firefox profile and installed from Firefox sync but the problem occurs. I deleted all devices in sync and added my 2 devices (desktop and mobile) again but it didn't work. Does anybody have a similar problem (and a solution)?

Hello everyone :)

From a folder, I have loads of Firefox profiles from different eras. I am looking for a way to export all the bookmarks of each of the profiles to an HTML file like the manual method (Library > Import and backup > Export bookmarks to formal HTML), but all in an automatic way by script. I like the HTML export from Firefox because it allows you to quickly navigate using keywords, either in links or in the folder names I gave.

Is there a simple solution that would reuse, for example, the same export code as Firefox ?

Thanks in advance With adelphity estebann

Basically, a requested relaunch blanked my profile and I can't get it back.

I have a lengthy workaround that will take over an hour to fix from backups, before this incident, but I'd really like to understand what's going on. How can my add-ons, bookmarks, history, logins, etc. be gone? If I did a refresh on purpose, why would my shortcuts remain intact? And, I started by backing up my profile folder to a neutral spot, so why isn't replacing it reversing the changes?

As background: The "about:profiles/Restart With Add-ons disabled" button brings up a small button dialogue to choose "refresh" or default "open." I selected "open" because I didn't want to fix my profile and assumed I would relaunch with only add-ons disabled, so this was a potential point of screw-up. I assume selecting "refresh" would reset application defaults and make a mess exactly like I find myself in now. Shouldn't "Restart with Add-ons disabled/Open" relaunch a temporary and reversible state? Doesn't "refresh" prompt a new default profile?

Considering evidence only, it appears I did something to roast my profile before I backed it up, but that's strange and really out in the weeds, and I'm assuming I wrecked it with my current activity.

The default profile name and path are correct. My shortcut links and labels that I use for a home page are intact but with icons missing, the same appearance as if I deleted the cache; is this detail part of application settings and not profile?

In the location bar (aka url bar aka address bar), the base domain name ("example.com") is displayed as normal text, whereas everything else in the url is displayed in gray. For example, if the displayed url is https://foo.example.com/bar, the "https://foo." and "/bar" are in gray.

Is it possible to get the whole url displayed as normal text, i.e., black, and avoid this "graying out" of some of it?

In my searches so far, I've found various other customizations for the location bar via userChrome.css, but not this one. Any help appreciated.

I'm using firefox 91.8.0esr (64-bit) as currently packaged for centos7 (x86_64), though presumably this is not system-dependent.

I use firefox since I go to college. When I got some problems, I try to check firefox use what to pick folder? I use Manjaro Plasma. I find chrominum use kdialog. But firefox looks not though both use gtk3 as UI

Firefox choose folder got wrong when use a USB HDD

In KDE 5.24.4, Linux. I started to have some issues with "Open containing folder" probably because I installed many Gnome apps which may cause bad configurations in my system.

I suspect this cause this issue even though I don't really have gnome file manager:

https://polywogsys.livejournal.com/309405.html "Gnome based file managers, Nemo/Caja/Nautilus provide the entry org.freedesktop.FileManager1. So it doesn't matter what you set as your default application for the filemanager mimetype - as per the freedesktop.org standard, firefox will always select a filemanager based on dbus (if it's there)"

But because the mimetype points to "dolphin", I dont really have other explanation either: $ xdg-mime query default inode/directory org.kde.dolphin.desktop

Hi,

is there a config option to prevent the showing of user/pw proposals when opening a website for which user account data is saved? When i'm logging into a website with already saved user data, i get account proposals (as ff saves the data "per domain", say if you have 3 accounts to one website, e.g. a test user, an administrator and a cms administrator, they are all presented where needed content may be...) see pict. I would like to opt out this behavior, as i have more than one website with 2 or more accounts.

I was using Ctrl+K on some websites to do things like site-specific search, task bars, and so forth, but recently Firefox started capturing it for focusing on the search/address bar (https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly#w_search).

Is there a way to unbind `Ctrl+K` in Firefox?

I just upgraded to Ubuntu 22.04 and along with that I upgraded Firefox. It's no longer possible to scroll the comment section of articles, just the main page. I've seen this on both the National Review and the NY Times. The scroll bar is also not persistent, it only shows up when the mouse is over it. Is there a way to fix this or is this a bug in Firefox 100.0?

Since a recent update the spacing of words in Firefox's UI as well as on some websites seems to be wider than normal (instead of a singular space it seems as if each space is now a tab wide). Additionally the numbers have also suffered and are now not presented in a normal font anymore but instead seem bigger and grey instead of white or black. Both of these issues occurred at the same time and appear on the normal User Interface of Firefox (e.g. in the bookmarks or in Firefox's settings and preferences) as well as on some websites/search engines. However when copying the text and numbers from Firefox into a regular text editor everything seems normal and no appearance issues can be noticed. What I've already tried: I've restarted my system multiple times since the issue first occurred. I've removed all contents from /home/user/.mozilla/firefox. I've reinstalled Firefox. I've deleted my cache. I've changed my font preferences in Firefox back to Default(Roboto) after having used Inter before. None of my actions above have changed anything. However, when I log into a different user on my computer and open Firefox there everything seems to be normal, so it seems as if this is a user-specific problem.

Thanks in advance, Emma.

Hello,

When I select text in Firefox the selection is not highlighted. The selection itself does work (e.g. deleting a selected word) but is not visible. The problem occurs in all fields where text can be entered, so the URL space, the search field but also text field on a page like this one. The strange thing is that the problem also occurs in Thunderbird.

I am using Ubuntu 18.04.6 LTS, Firefox 99.0 and Thunderbird 91.8.1
