Diễn đàn hỗ trợ Firefox

It worked nicely for many years, until today. I installed Supraland from Steam, played for a couple of hours, and suddenly my Youtube page went glitchy - not the layout but minor elements were getting scrambled, especially text. I'll attach a couple of pictures to show it. In fact, all pages glitch if their content changes even a little. As of typing now, I see the glitches, with a word or another getting butchered. Gifs and videos are full of that.

Windows 10, the current update, Radeon RX 580, the recommended AMD drivers installed (and reinstalled again and again, 23.11.1)

I think I did pretty much everything with Firefox. Disabling hardware acceleration fixes it (but then of course the browser goes slow). Games work fine, including Talos Principle 2 which is intense enough. The clean install, reinstall and all that. I'm writing from the beta stable build now. I've tried to regress to the previous versions too.

It strictly coincides with the game installation but I have no close backups - who knew that some game might just do that. Then, of course, I tried to uninstall it too.

Thoughts?

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?

previous version of firefox , open with option work perfectly. But latest update , it won't work anymore such as potplayer://url... i don't know why but this is working perfectly on other browsers such as chrome...

For some reason, Firefox just stopped working yesterday. The only way I could get it to work again was to uninstall and reinstall (the refresh option did not work). However, now I've lost all my bookmarks, passwords and customization. I don't care about the customization and losing the bookmarks is an annoyance, but I'd REALLY like to get my passwords back. The installation created a folder of Old Firefox data, but when I open the folders that I think might be helpful, like bookmarkbackups, they are empty. Is there anywhere else I can look where these might have been saved? I did not have a Mozilla account so no profile until now which I just set up in order to access the forum. Thanks for any help you can provide.

Every time I open Firefox after closing it, I get the message below. I can click the button to restore session and it works every time. With each update, I hope to never see this message again, but after installing a new version on Ubuntu today, I see the same familiar message. This is not linked to a computer, or an operating system because I've seen this on both Ubuntu and Mac. If Firefox could literally just click the button that would be awesome.

Sorry. We’re having trouble getting your pages back.

We are having trouble restoring your last browsing session. Select Restore Session to try again.

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.

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.

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.

How to SWITCH TO TAB when i enter something in address bar and I have this page opened? When I search my question, I get answers like "how to DISABLE...", but I need to ENABLE this feature. Firefox 122. When I type in Address bar something like "google.com" and I already have opened this site in another tab, I want FF to switch this tab instead open a new tab/window. How can I ENABLE this feature?

Good evening,

I have a new laptop, from the same brand and make as my old one, both are HP pavilion with the same configuration and only 2 years in between! I have been trying on and off for weeks, to synchronise my FF browser, with all open tabs, history and bookmarks, but all to no avail. I do everything the sync instruction tells me to do, but nothing happens. I am getting desparate, because my old laptop has a problem (hardware, nothing that could prevent synchronising) and is still under warranty, but time is running out!

Will anybody help here, and how do I receive answers?

Hello,

I'm using firefox 122.0, 64bits, on windows 10.

Since a few days (issues might be older, I have not used those site in a while) I canot watch netflix, I get the aparently infamous error code F7121-3078, which aparently means my browser is out of date, which it's not...

I also canot use musescore anymore, https://musescore.com/user/166080/scores/359836 for exemple, the page load halfway and then I get a firefox error that this page is slowling it down and ask me to close it. It's the same for every single music sheet, the rest of the website works fine.

I've tried to use troubleshoot mode for both website, and it's not working. I'm runing out of ideas so I've come here for help.

Thanks !

I am logged into my Mozilla account on four devices: Laptop Linux, Desktop Linux, Desktop Windows, Phone Android. However, when I try “Send tab to device” or list the devices in the account settings, the two Linux devices are not shown separately, so I can’t send a tab from Laptop Linux to Desktop Linux or vice versa. In fact, when I edit the Device name on either of the Linux device, that name will also be shown on the other device.

How is this possible? How can I disentangle the two devices?

I am running v122.0.1 on a Mac and since the last update if I open a Facebook Messenger message which pops up at the bottom of the screen clicking the minimise or close doesn't do anything and the message stays on screen The only way to get it to close is to log out of Facebook and then log back in again. Is this a bug in this release?

Hi. I am running a 3 monitor setup and I like to keep open quite a few tabs. And two windows of Firefox. So two Firefox instances with several tabs on each. But because it eats a lot of memory, I have to close and reopen Firefox from time to time. And to my annoyance, sometimes it "forgets" about one of the windows. So opens only one instead of both. Therefore I loose some quite important tabs. Any suggestions on how to fix this? Thank you.

This is the error message.

'An Error Occurred

Oh, no! It looks like an unexpected error occurred. We've already notified the site administrators. Please try again now, or in a few minutes.

I have tried resending numerous times since last night with the same result.

Version 122.0.1 Firefox Release February 6, 2024

I have the HTTP_PROXY, HTTPS_PROXY and FTP_PROXY (and their lowercase counterparts) exported and then the firefox binary is started from the shell script. The settings in firefox say it will 'Use system proxy settings'. Nevertheless I do not see the proxy being used as I can not access the web pages that need the proxy. The 'about:config' also does not show that firefox picked up any proxy related information from the shell environment.

I know the proxy address is correct because if I use brave browser instead of firefox (same shell script that launches brave) I can reach the web pages behind the proxy as expected.
