Firefox Support Forum

Hi,

Back in the old days of classic extensions, they had access to FF's GUI elements, provided such privileges were asked in a manifest file.

For example, there were extensions that added tab's title to the URL bar. And I want to do exactly that nowadays, too.

WebExtensions can not do that but this should work with userChrome.js, right?

If so, maybe someone has already done it and I simply could not find it. Does anybody know?

If not, then how do I access the URL bar object to add text (e.g. page's title) to it or something else?

Thanks in advance.

found a bug with firefox 101.0b5 website https://www.express.co.uk/ it does not display the comments for an article. Works with Microsoft Edge

I'm having an issue where firefox is acting as if there's something blocking pages/content. I do not experience the issue on any other browser.

I first noticed it trying to log into one of my accounts. The login portal redirects the page to a success screen and then to the home page. With firefox after entering credentials it shows a blank page with a 500 error instead.More specifically I believe it has to do with an api for "duosecure" (checking for multi factor auth)

another example is trying to download chrome remote desktop - normally you click their download link and pauses the current page while it triggers a popup to chrome's page to download the extension. It does this in any other browser I try except firefox.

This is on a clean install of windows 10 and a clean install of firefox. I am on the latest version of firefox (tried 106 and updated to 107 via the beta options) I have: - cleared cookies and cache - restarted firefox - tried safe mode - tried with and without extensions/addons and have removed all - uninstalled firefox as well as deleted all appdata folders - tried unchecking hardware acceleration - setting dns to none and changing the dns server options - turned off any setting i could find regarding popups, blocking sites etc - manually turned off enhanced tracking - gone through windows firewall and security settings to turn off everything that i could find that was "on" - rebooted computer - rebooted router - used the "refresh" firefox to set it back to defaults - tried connecting to the internet via ethernet and wifi options - windows updates Note: logging into other things such as gmail or facebook are fine on firefox but they don't seem to trigger redirects to outside sites.

Is there any way to rotate between different screen sizes option using shortcuts keymaps which appear during "responsive design mode" is on. I found extensions which resizes whole browser & they helps. but it also causes developer tool to resize along with browser which hinders me to see different css properties. so i am looking for a way to rotate only screens.

"Responsive Design mode" is what turns on when we press ctrl+shift+m.

I Love using firefox more than Chrome. This is my go to browser.

Hi,

I have a problem, which only seems to apply to Firefox. I am a developer for a site which uses LetsEncrypt certificate. When I access it via Firefox (and only Firefox), I get the error message as mentioned in the subject.

I tried to understand why this occurs. A quick Google just leads me to an issue with the Microsoft domain, and what I can understand was a Firefox bug.

Trying to figure out if it is a problem with Firefox, or a problem with the certificate. Any thoughts?

Steps to reproduce:

1. Have Google as the default search engine.

2. Type a search string into the address bar.

3. The address bar briefly shows a URL for the Google Search results.

4. The address bar is very quickly overwritten with the original search string.

See screenshot for example.

How do I stop step #4 happening? I want the URL to remain in the address bar, for example to be able to give somebody a link which executes the google search.

I think this is new in FF121.

Whenever I sign into Firefox, all my themes, add-ons/extensions are added via Firefox Sync. That's fine, but the problem I have is that whenever I sign into any Firefox browser, an old theme I used to have that I no longer have on my account keeps coming back, and I've tried to find solutions to this issue, but none have had this kind of issue. It may be similar to issues those have had, or currently have, but I can't seem to do anything to remedy this issue.

Keep in mind that this is not a Firefox browser issue, it is an account issue.

I'd be deeply grateful to any assistance you may have for me.

When I attempt to open Email after opening wowway.net in Firefox, a new window opens at "http://wowway.net/files/wow/login.php?bounceto=http%3A%2F%2Fwowway.net%2Fzmail%2F%3Fautologin%3Dtrue" and the screen only contains this message: "Please wait while we are logging you in." It never logs in. Wowway.net says the problem is with Firefox and instructed me to use Microsoft Edge to connect to wowway.net and that does work OK. When I click Email from wowway.net in Microsoft Edge, it correctly connects me to "https://email.wowway.com/modern/" from which I can access all my email.

PLEASE HELP! I want to access my email with wowway.net through Firefox as I have for years.

Thank you, Kent Holcomb kentmh@wowway.com

Sometimes when starting Firefox ("developer edition", running on Ubuntu 20.04, Gnome shell, X11 windowing system) it appears 80% full screen -ish, but actually the window is full screen size - you just can't see it. It flashes really fast, and doesn't repaint correctly. It's very hard to get rid of it as you're never sure what you're clicking on.

Restarting it a few times and I get lucky and it works. I think this problem has gotten worse over the last few months.

I believe it might be something to do with the anti fingerprinting, but I'm not sure. It's making it unusable for several friends, but I'm a bit more stubborn so I'm looking for a fix.

i have found themes and extensions that make the bar transparent but i want the full the whole window transparent meaning i want to see through the firefox window .

So I downloaded Firefox and logged in expecting my bookmarks to carry over after I "sync'd" it, however the did not. So I went to my old pc and did the export bookmarks thing and imported it to the new pc.

Now.. I have all my bookmarks and everything appears great. Except whenever I open a link from say my work it opens a Mozilla window that doesn't have my bookmarks. When I try to combine the windows It doesn't let me. I am also scared of losing access to the Mozilla with my bookmarks as I work from home using those. (the desktop shortcut to Mozilla opens the one without all my work)

In the attached screenshot things to note, the bookmark bar available on left isn't there on the right. Additionally in the taskbar (bottom) it shows Mozilla in two distinctly separate icons. When two Mozilla windows are open, they share the same icon on the taskbar, these do not, which leads me to believe I have two incompatible versions existing next to each other.

ok my problem is: before: https://i.ibb.co/gdBssLZ/Image-224.png after: https://i.ibb.co/fSY8RHf/Image-241.png

my firefox take up more space, even my addons dont fit the way it was. its very annoying, how can i make it back?

Every time I work on the local environment a lot of my extensions go crazy on localhost, throwing enormous amount of errors. This makes console barely readable. Is there a way to disable messages thrown by extensions in the developer tools of Firefox Developer Edition?

Similar to this in Chrome with "Selected context only": https://superuser.com/a/1346827

Thanks.

When I close a tab, sometimes it crashes. I tried with `-safe-mode` and the error persists. Let me know if I can add more information.
