Firefox Support Forum

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.

Since the new update for some reason, videos on some websites are no longer loading as they used to. The big sites like YouTube and Netflix are fine though others are giving error codes.

(Error Code: 102630) is a common one, even after going through the guides online to get it working nothing works.

The other thing I've noticed is: Error code: SSL_ERROR_RX_RECORD_TOO_LONG This also comes up on some web players. Same again, nothing works trying to fix it.

Something changed during update 122.0.1 ?? Any Help or Ideas would be great. :)

GOOGLE CHROME WORKING FINE BUT FIREFOX AINT WORKING

THANK YOU

Hi. Is there anyone having experienced similar phenomena?

1) Firefox stops showing Gmail correctly after a few days. Immediately after starting Firefox, I can log-in and open Gmail.com correctly. But after a few days keeping opening Gmail on Firefox, Gmail.com shows error messages regarding Cookie (please see the attached screenshot). If I do "Try clearing the startup cache" from trouble shooting information tab, Firefox shows Gmail correctly again, but after a few days the same issue happens again.

2) Fire fox cannot log-in on Outlook.live.com. As title says, I cannot log-in outlook live. Whenever I try to log-in from Outlook log-in page, Firefox shows log-in page again. This issue isn't resolved by inactivating "Enhanced tracking protection".

Both of them started to happen since the update around the end of 2023, I think. (On the other hand, Chrome works on both websites correctly)

If you have some information, it might help me. Thanks in advance.

I keep getting a 404 error for a website even after clearing data and cache. I can access the website on other web browsers like chrome and on my cellphone but not firefox

When the system theme (light/dark) is switched globally, Firefox recognizes this and also switches its theme automatically (if configured appropriately). This should also retheme addons opened in the sidebar (Tab Stash or Sidebery for instance), and it does so under certain conditions, namely if either a) no sidebar was opened when starting Firefox and the addon sidebar window is opened directly, or b) the sidebar was opened with start of Firefox. Unfortunately, no retheming of the addon window occurs when some other Firefox sidebar (such as bookmarks or history) was opened after Firefox start and before system theme switch. In that case, the addon window (which is opened as the system theme is switched) does not retheme. This can be mitigated by either restarting Firefox or by opening a Firefox sidebar such as bookmarks or history, and switching back to the addon window.

So to reproduce this behaviour:

1. Open Firefox and some sidebar addon directly (such as Tab Stash in my case, with Ctrl-Alt-S)
2. Switch system theme globally (I do this with Night Theme Switcher in GNOME)
3. Observe that Firefox correctly redraws the addon window
4. Open bookmarks (Ctrl-B) or history (Ctrl-H)
5. Reopen the addon window
6. Switch system theme globally again
7. Observe that Firefox does not correctly redraw the addon window
8. Open bookmarks (Ctrl-B) or history (Ctrl-H) again
9. Reopen the addon window
10. Observe that Firefox redrew the addon window

This has already been reported to the addon developer, who stated that it might be a bug in Firefox, since his addon only tells Firefox which colors to use in which mode.

System details:

• OS Version: Linux 6.7.4-arch1-1
• Browser Version: Firefox 122.0.1
• Desktop environment: GNOME

In what scenario would anyone ever want a website to track what they are copying? Why would a browser allow a website to see what you're copying anyway?

Not only that, it takes up precious real-estate in an often already-crowded contextual menu. Why not make it the default action when selecting the normal "Copy Link" contextual menu item?

Hi, on my current Firefox setup, I have a search engine shortcut in my Top Sites on a New Tab page. It's a quick one for Amazon, I can't figure out how to add others though. I saw reference to it in this old support issue, but I can't find how to do that anymore.

All of a sudden (started today) Firefox will not load ANY websites, except Mozilla/firefox websites. All previous bookmarks, links, and typed in addresses do not load. No changes to virus protection, browser, or any other updates. Other browsers (chrome, opera) work fine.

After updating to Beta 122.0b3 (64-bit), the active tab is now highlighted with a simple white outline instead of the coloring surrounding the address bar. My selected theme has not changed, and the same goes for all of my extensions. I could not find this change in the 122.0b Release Notes.

If this behavior is intentional, is there any option to return to the previous behavior (including in about:config)?

Hello,

I've encountered a recurring issue with Firefox on Ubuntu where my master password is sporadically not recognized when typed using my external wireless keyboard. This problem does not occur consistently but is particularly frustrating when it does, as it forces me to switch to my laptop's keyboard for input. I'm certain the password is entered correctly; after multiple careful attempts (3-5 times), the issue persists, leading to unnecessary stress and inconvenience.

• • Environment:**

- **Operating System:** Latest version of Ubuntu - **Hardware:** Dell Latitude laptop with a Contour external wireless keyboard, connected through a Dell docking station. This setup is shared with another laptop (HP) via the docking station.

• • Observations:**

- The issue seems to occur sporadically and is not reproducible on demand, adding to the frustration. - It has happened notably on the first login attempt after the computer's first boot of the day. - On one occasion, the problem led me to change my master password under the mistaken belief it had been compromised.

• • Impact:**

This intermittent recognition issue disrupts my workflow and significantly affects my user experience with Firefox. The necessity to switch input methods and the initial misinterpretation of the problem as a security concern are particularly concerning.

I hope this detailed feedback assists in identifying and resolving the issue. Thank you for your attention to this matter Firefox.

Sincerely, Daniel

i made a custom firefox colour setup for my desktop machine, and it doesn't have any option to save it- because of this, on my laptop which is synchronized to my desktop's firefox settings, it is not showing up at all and if i go to firefox colour it isn't there for me to add. so how do i DO this???

i do not want to maker my custom setup public so it is not available to all, it is my own setup using some of my own artwork which i do NOT want made public on the internet.

there MUST be a way to save it however and let my laptop's firefox also display it,m yes???

and on that topic, why isn't it just automatically synchronizing when everything else does?

I just wrote this blog post and someone suggested I contact you.

I have my default browser set to Firefox on Linux (Debian Bookworm). When I open an http:// or https:// URL, it opens in Firefox, but when I open a file:/// URL, it opens in Chromium. It seems that file:/// URL makes it resort to the MIME type.

Is there anything Firefox can do here or is this a Debian or freedesktop.org issue?

Thanks!

Tim

Firefox is broken. For months now anytime I watch a Live stream on Youtube it freezes within seconds and acts like it's buffering. Internet connection is great. Same live streams work perfect on Microsoft Edge, Google Chrome and others. Only Firefox browser is doing this.

When I save new bookmarks I can't find them to open them. The list of folders I see in the "Choose . . ." selection is different from the list of folders l see when trying to open a bookmark. The bookmarks seem to be saving in one list but opening from a different list. How do I replace the list Firefox opens bookmarks from with the list the new bookmarks are saved in?

Hi everyone,

I'm used to typing one or two letters into the address bar and then the down arrow to access the same handful of websites every day. A few weeks ago, Firefox started randomly moving these around so that the same letters that have always made it open the same URL now opens a different URL and I have to actually search the suggestions. How can this annoying behaviour be fixed?

(a few months ago, the address bar wouldn't delete entries, but this problem vanished as mysteriously as it appeared)

I gather there can be different kinds of screen flicker and many causes. My problem is with one particular website, https://www.yucatan.com.mx/ , and it didn't used to happen. When I open the site or pages in it, trying to scroll down just results in continuous, rapid flickering and no scrolling. I have to pull the scroll bar down just enough to get the page started, and then the mouse scroll wheel works. After looking at other people's similar issues, I have tried disabling smooth scrolling and the pop-up blocker. When I open the same site with a different browser and try to scroll down, I do see about two frames of flicker, but it's almost unnoticeable, and scrolling works OK. I restarted Firefox in troubleshooting mode and was able to get it to behave like that other browser at this site -- just a momentary flicker and no interference with scrolling. OK... where does that leave me? I can't use troubleshooting mode all the time. And it's just this one website that presents the problematic behavior. Thanks for your thoughts, -Rick
