I am not able to sign in to the Mozilla add-ons page. When I click the login button, a new page is shown with my Mozilla account email, picture, and a sign in button. After clicking "Sign in" I expect a page to appear to input my authenticator code, but instead what appears is the window in the attached partial screen shot. Any ideas? Thanks!

This is a problem that I have since months, still unresolved. If I try using a different browser (like Brave) it works, so it's a Firefox issue or Apple issue with Firefox.

Basically if I go to https://web.goodnotes.com/login and I login via iCloud, a window opens up which asks me iCloud email and password, then it asks me for the sms code received, then I put it and then I get a BLANK page (the image that I uploaded) with in up right corner "Login performed as my name". And then nothing happens. But instead with Brave it opens up the Apple authorization to accept the Browser and then I finally can enter in Goodnotes web. With Firefox I'm stuck in that blank white page.

Since it's an issue that I have since months, I think I should report this and here I am.

Hello, For whatever reason, I can't view Youtube livestreams or movies, and the quality on regular videos is limited to 360p only (with some offering the upgrade to 720p - though this often causes the video player to freeze). I've tried disabling my adblocker, my other various plugins, even opening the blocked content in a private window or troubleshooting mode - still no dice. Is this yet another one of Youtube's anti-firefox tricks? is there any way to fix/bypass this?

I would like to select and delete a subset of user names and passwords in Firefox. I have a group of about 80 logins for an old account which I no longer use. I know I can delete individual logins one at a time but doing this 80 times is a pain!

I can search for the particular account in the password list and Firefox lists them all, which is great. What I would like to do then is right click and select all followed by delete.

Is there a shortcut somewhere?

For some reason I updated to win 11 and now Firefox won't let me login to mercadolibre, it will display the login screen, take my username, send me to the password window, enter my password but won't go anywhere from there. The curious thing is that Edge will log me in without any issue and if I do the same thing with Firefox using a private windows it will let me login but Mercadolibre will always ask me to scan a code with my phone which makes the process longer and tedious.

I cleared all the cookies from my system to no avail.

How can I set tabs to automatically preload when I open the browser? I'm just trying to switch from Chrome to Firefox and I can't find such a setting here, although it is a very convenient functionality. I mean that when I open the browser, I can click on any of the tabs and it will be (partially or completely) immediately ready to work without additional loading.

Installed Firefox 122 in a new Windows 10 installation and added some extensions (e.g. Gesturefly, Update Scanner, uBlock Origin, Uppity). These pinned fine on my old installation. But I cannot find how to pin them on the new.

All the help I have found Googling, or using search here, says go to the Add-ons Manager page and right-click the extension and use "pin to toolbar". Alternatively click the extension and click the gear icon and use "pin to toolbar". But when I right-click there is no pin to toolbar context menu entry. If I left-click the gear I get "Check for Updates, View Recent Updates, Install Add-on From File, Debug Add-ons, Update Add-ons Automatically, Reset All Add-ons to Update Automatically, Manage Extension Shortcuts". If I right-click the gear I get a line of icons (left, right, reload, star) followed by "Open Image in New Tab, Copy Image Link, Email Image, Save Page As, Select All, View Pate Source, Inspect Accessibility Properties, Inspect (Q)". If I right-click the extension in the Add-ons Manager page itself, I get a very similar list. In no case is there a pin to toolbar option.

How do I pin an extension, given the above? What have I messed up?

I'm trying to use a manual proxy server for Firefox. When entering the proxy address and port number, Firefox outlines the port number field in red and disables the OK button thus refusing to accept my assigned port number. I'm trying to use port number 29842 which was given to me by the proxy provider.

So I've been doing this for years now, as a Youtuber I take an image file from File Explorer (Windows 10) and drag it over to upload the thumbnail to Youtube. But for some reason the last few days I can't drop the file, it just stays there with the mouse when I let go of the button. On a random page it should let me drop the file and show the image but it doesn't, and it also won't drop if I try a google image search.

I have tried this on Edge and Chrome and the problem only seems to exist on Firefox.

[My screenshot button hides the mouse in pictures but it's attached to that blue semi-transparent square, trying to drop a file but can't.]

I am having an issue where youtube videos played at higher quality stutter when put to fullscreen. Up till about 720p60 works fine, at 1080p60 and above the framerate becomes unstable.

Things I have tried: - I have tried going into media.media-capabilities.enabled and changing it from false to true - I have set network.buffer.cache.size to 262144 - I have disabled all my plugins - I have tried changing my user agent to windows/chrome

My current setup: Firefox 122.0, Macbook pro Sonoma 14.1, Apple M1 Pro chip

Curiously, if I make a new firefox profile and play a video there, there is no stutter. Does anyone have ideas on how I can fix my current profile?

Firefox is my default browser, but it does not allow me to log in to specific websites. For example, ihg.com, when I click the sign in button nothing happens, I just have a little note at the bottom left "javascript:void(0);" Another example, dutchcrafters.com , when I click Log in with Gmail, nothing happens.

I have tried removing all the content blocking extensions (privacy badgers, ublock origin, etc.), did not fix it. I have tried a firefox refresh, did not fix it. I have tried uninstalling and reinstalling firefox with several device restarts, did not fix it.

I know this must be a firefox specific problem because microsoft edge work perfectly for both of these examples. Any other suggestions to fix this firefox issue?

I thought I had two different accounts. Home, with my personal email and work, with my work email. My work computer crashed a few months ago, and out IT department was able to recover all my bookmarks, but it wasn't easy, so I was told. I decided to do what I do at home and that was to create an account for work, which I did. I now have an account for home with it's own bookmarks, and email, and a work account with it's own bookmarks and totally different email. I recently got a work phone. In the process of setting it up I synced it up with my work account. when I came home tonight I got online and all my work bookmarks were on my home computer. How did this happen? Now I don't have my home bookmarks. I tried signing out and signing back in with my home account, but no luck. This is very frustrating especially since they are two totally different accounts. SO, how do I get my home bookmarks back on my home computer? Thanks

Hi, Avast Antivirus keeps giving me this warning every few minutes. I have never visited the site in the URL and it seems to keep appearing regardless of anything I do. Is anyone else getting this? Does anyone know how to fix it?

Thanks.

Texting images via Google Voice had always worked in the past.

Now it does not in FF, but succeeds in Chrome. "Server error" is the FF response.

What has changed? Latest FF on Win11.

I encounter this message "Peer’s Certificate has been revoked. Error code: SEC_ERROR_REVOKED_CERTIFICATE" when connecting to "Site A" using Firefox version 122.0 (64), my primary browser. I have successfully connected to "Site A" using Firefox in the recent past.

I can connect to "Site A" without errors using my backup browser, MS Edge Version 121.0.2277.83 (Official build) (64-bit).

This seem to be a Firefox related problem.

I have been trying to solve this problem on and off for about a year now, but 99.99% of the time I try to access https://en.wiktionary.org/ , I get the following error: Secure Connection Failed An error occured during a connection to en.wikitionary.org PR_END_OF_FILE ERROR Error code: PR_END_OF_FILE_ERROR

I have NEVER gotten this error message for any other website. And the strangest thing? Sometimes I CAN access Wikitionary with zero problems, but this phenomena tends to only happen when I attempt to access the website very late at night or really early in the morning. I cannot think of a single thing I have done differently when this happens.

By the way, I am able to access Wikitionary from Microsoft Edge just fine, it is ONLY Firefox where I have this problem.

I restarted my computer today and downloaded a new version of Firefox. When I started it up again everything was gone... all Tabs, history, and bookmarks. This is a sad loss as I have been organizing my life with Firefox for over 10 years. Is there any going back and getting my firefox restored?
