My system broke during an update. Now I want to import my old Firefox userdata, but everytime I try to use the old data firefox just forces the creation of a new profile?

Is it completely impossible to recover data not created with the same firefox version?

There used to be an extension called "IE Tab". It allowed you to right click on the link, and open the site in a tab, using Internet Explorer, for sites that didn't work properly in Firefox. I was wondering if anybody knows of any similar extension that would do the same for Edge? I can't open Twitter (X) using Firefox anymore, but I can open it using Edge. I don't like Edge (obviously), but I have no choice. Thanks in advance!!!

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.

Something went wrong w/ the mouse, some of my tags disappeared & wasn't able to recover them via Ctrl+Z, so I decided to perform my 1st [Restore] (never had to do 1 before), since I had just recently done an [Export Bookmarks] & a [Backup]. Everything seems to have gone Ok, except that for every tag, all of the bookmarks listed under the [Name] column are duplicated. When I right-click & [Show In Folder], they both show in the same folder. When going onto their folder, they are only shown once, so there are no duplicates there. When I attempt to [Delete] 1 of the 2 duplicate entries they both get [Deleted], so I can only conclude that they are 1 in the same. But the question remains, "How can I fix this duplicate condition?"

Another related & interesting behavior is that, from any bookmark folder where you can clearly see there are no duplicated bookmarks, when you do a [Search] from the top-right-hand search-box, the "results" are also "duplicated", although you might need to sort them by clicking on the [Name] column control. So, I can go to any bookmark folder & clearly see that there are no duplicate bookmarks, but when you do a [Search], that's when you get duplicate entries. That leads me to believe that this is the result of the [Search] function, & thus for some odd reason the [Search] is generating "duplicate entries". And then perhaps, both the [Tag]s & the [Search] function are related.

Also, this "duplication" does not happen on newer added bookmarks, after the [Restore] was executed, & it's only a phenomenon that affects those bookmarks that were saved by the Bookmarks' Library [Backup] function, & thus this anomaly was introduced by the [Backup].

Actually, I just realized the problem is more complicated than I thought. The reason any search results in "duplicate bookmarks" is because there are 2 sets of folders, 1 set above the other, & if you don't scroll down all the way you won't see it. So that's why there are actually "2 Sets Of Bookmarks", because there are "2 Sets Of Folders", 1 above the other. The problem is that when you delete any "Duplicate Bookmark" you delete them both, & not just 1 of the 2 bookmarks.

I wonder if it would work, to "Delete All Bookmarks" & then do a [Restore]?

Could "Mozilla Support" answer that?

Don't know why every time I attempt to [Post A Reply] & get an "Error",... So I'm going to post my reply right here,...

Fix: (2024-02-19) Of course, I did some testing before I concluded what was the best approach, but since I noticed all of the "Bookmarks Folders" were duplicated under [Bookmarks Menu], an easy fix is to go to the "bottom duplicated folder", right on top of the [Other Bookmarks] folder, & "Select It" (by clicking on it) & [Delete] it (w/ the [Delete] key on your keyboard). Do this 1 by 1, until you reach the "bottom folder" of the bookmarks' folder you certainly don't want to delete. Close Firefox & then reopen it - to make sure Firefox takes care of any garbage-collection. Then do your Bookmarks' Library [Export Bookmarks To HTML] followed by a [Backup], & you are good to go.

Actually, I don't know what introduced the error. Don't know if it was Firefox's [Restore] function, or it could have been me (by accident) w/ some "unnoticed & unexpected" move of the mouse/trackball, which accidentally duplicated all of the folders w/o me noticing, & that is why all of the "Bookmarks" were "duplicated".

Happy Firefox Browsing,...

I have updated to the latest version of Firefox browser this time. Whenever I create a new tab, the page will prompt me with a failure to load content and hope me to try refreshing to resolve it, but it does not work

Starting with Firefox version 120, you can set Firefox to automatically launch whenever you start or restart your Windows computer. https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer

The browser shows opt-in prompt for the user to easily setup this behavior. However, I do not want to do this.

When I click "No thanks", the prompt goes away, but couple days later, it returns. I guess that an update resets the prompt status.

Is there a way to permanently disable this opt-in prompt without allowing Firefox to start automatically with the computer?

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

Hi,

What is the area above toolbox called (Firefox, File, Edit, View, History, Bookmarks, Tools, Window, Help) and how do I change color on just that?

Thank You, Leslie

When composing emails in Gmail holding down a (any) key does not activate key repeating.

Also, the there are irregularities when using discover.com in Ver. 124. When editing my customer profile, keystrokes are not recognized. Nothing happens when typing. I also had difficulty signing-in; this may be coincidental.

Things tried: (1) A different keyboard. Same results. (2) Firefox version 122. The key repeat function worked in Gmail. I could edit my profile at discover.com. (3) Uninstalled and reinstalled ver. 124. All problems persisted. (4) Ran Ver. 124 in troubleshooting mode. All problems persisted. (5) Launched newly downloaded versions of both 122 and 124 (from command line) and ran them simultaneously. The problems persisted in 124 (troubleshooting mode), but 122 worked well. I used two different keyboards with no difference noticed. (6) Downloaded and ran Chromium. All worked well.

Hi there,

On Firefox, I'm experiencing "momentum" scrolling where, when I scroll using the trackpad, after I lift my fingers off, it keeps scrolling for a bit.

This is not the same thing as smooth scrolling. Disabling smooth scrolling does not disable this behaviour, and I use smooth scrolling on plenty of programs without it experiencing this "sliding" "momentum" on any of them except Firefox. I've also used Firefox before with trackpads without experiencing this.

How can I disable this?

Currently, there appears to be only one option to tell Firefox to open a given site in a specific container; that is, from the URL bar, to the right.

Would it make sense to have this configuration option presented in "edit bookmark" and/or in a right-click pulldown menu "Always open in this container"?

I use a public computer often, and I would like to use certain customizations while remaining anonymous. Rather than going through and clicking a bunch of checkboxes, I decided to have a hot key combination to enter in order to obtain my desired options. For example, I want to allow new windows to open normally, I want to choose where files are saved, and I want to turn off Firefox's recommendations. The underlined hotkeys are, respectively, ALT+W, ALT+A, and ALT+R ALT+F. So rather than a bunch of scrolling and clicking, I could just type ALT+WARF, and get the options I want quickly.

However, pressing the hotkeys while in the settings does not seem to do anything. In particular, pressing ALT+WARF only succeeds in pressing the ALT+F, which opens the File menu. Pressing these keys without an ALT key sends them automatically to the search bar -- which is also not what I want. Pressing ALT+SHIFT focuses in on the checkbox -- but does not press it. For example, ALT+SHIFT+W focuses on the checkbox, but I still have to click SPACE after it to press it.

Is this a bug? If not, how can I make the underlined keys press the respective checkboxes?

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.

I can not log into my Harley ride planner account. Its not the websight as I can log in on my I phone. I get this message.The resource at “https://www.harley-davidson.com/etc/designs/h-d/images/dropdown-arrow-white-2.png” was blocked by OpaqueResponseBlocking. Reason: “nosniff is true and mimeType is an opaque-blocklisted MIME type or its essence is 'text/plain'”. How do I fix this? Thank you Paul

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

Hi! Relaying this for another Firefox user. Whenever they go to Google Images, it seems like the images don't fully load. GIFs don't play, and it ends up showing the preview rather than the full image. This isn't happening on other sites like Bing. Any ideas what could be causing this? A uninstall and reinstall didn't help.

Thank you so much!
