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?

We are deploying Firefox installed via the v122 binary on Ubuntu 22.04.4 Server w/ubuntu-desktop-minimal --no-install-recommends (we need to have no-user-interaction install). We are using an Ansible playbook to copy over and unarchive the tarball, then create a firefox/distribution folder in the install directory and copying a profiles.json file to said folder, links the install directory to the /usr/bin/local directory, and setting firefox.desktop as the system default browser.

Using the instructions from: https://mozilla.github.io/policy-templates/

What we are hoping to accomplish is the user who has never launched Firefox will click on a link in an application, which will launch Firefox and go directly to the requested page. As it stands right now, the first time a user clicks the link, it launches firefox and shows a start page. The user must then close this window, and click the link again. This brings up a "Use Firefox as the default browser" prompt, which the user must accept, but then does not display the link. The third time the user clicks the link, the requested page pops up, and works from this time out.

We would like to have this be a one-click experience for the user. Looking at the options in about:config after getting firefox to launch, it appears firefox is not getting the options from the profiles.json file. Are we missing something about placement of this file? Missing some lines? Should we be using AutoConfig instead? Thank you for any assistance!

When I try to access my payment preferences page on xfinity.com, the page goes blank and it appears that it is being blocked. I can't figure out how to unblock it. I had to use Microsoft Edge to access the page to change my information. Can you please assist?

I am no longer able to add attachments to gmail or upload images or attachments to websites. When I click on the attachment icon or upload button, my finder window does not open. However, it works in other browsers. How can I fix this?

I have Yahoo as my home page and usually search from it starting out. I noticed, however, after the last update or two in the last week that when I hit search, it opens the search results in a new tab. It didn't use to do this, but I can't find any Firefox option to make the searches stay in the existing tab. Can anyone help with this? I don't think it's Yahoo's settings, because I'm not signed into it. It seems like the Firefox update created this new behavior.

Today when I close many tabs using control w firefox seems to randomly jump around when choosing which next tab to close

I wish to have firefox always close the adjacent tab to the tab I just closed

This should be the default behavior ... I do not see any setting for this ... is there an addon to do this ?

I am using the latest firefox on ubuntu

• • • UPDATE*** below answer for setting `browser.tabs.selectOwnerOnClose` has no impact on this

Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

How to reproduce the bug: Jump to the address bar, and then press shift, ctrol, alt or windows_start, you can see the address getting deleted. You can also see it in Google Sheets and Microsoft Excel Online, it just deletes the cell, or a selection of multiple cells. --Interestingly on Google Docs it doesn't delete but just move the cursor to the first character when a string is selected.

 It happens only once per mouse click, or focus change

What I expect: Shift, Control or any mod key should not delete content or move a cursor

Thanks!

I'm not sure how this happened, but one of my firefox web pages keeps zooming in only on one website and the zoom refuses to reset no matter what I do.

For reference this is wikipedia. Every time I load a wikipedia page it loads zoomed in to 210%, which I will then have to reset to 100% in order to read the page properly. If I for some reason click on a link on the wikipedia page that goes to another wikipedia page, the zoom will reset again to 210%, which I will then need to reset once again. This happens also whenever I switch from the wikipedia tab to another tab and then switch back again. I do have an addon that changes wikipedia slightly (the Wikipedia Vector Skin addon) but disabling this addon doesn't fix the issue.

I went into about:config several times already and changed different settings to try and make it stop, but nothing so far has worked. I've tried resetting layout.css.devPixelsPerPx to 1.0 and back again to -1.0 and it makes no difference. I also tried changing browser.zoom.full to false and it keeps happening. Changing browser.zoom.siteSpecific to false does fix the issue, however it also resets the zoom I have on other websites that I want to keep, so it's not an ideal fix. I also cleared all my cache and cookies and it changed nothing.

Does anyone have any idea on why this keeps happening only with wikipedia, and how I can get this to stop happening? I assume there must be some internal setting that would need to be reset in order to fix this, but I don't know how to do it or where I would even go.

After I want to multitask on my phone and switch between the browser and other app. The page becomes blank and refresh button doesn't work.

I need to open a new card to continue using the website loosing all temporary changes made to it.

Issue was present for at least 6 months.

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, whilst chromium renders it correctly, firefox struggles to cope with combining diacritical marks (two unicode characters instead of a single one - but should have look the same once rendered)

I tried to log into my pocket account, but was redirected to use my Mozilla account, and none of the articles I saved over the last decade or so are showing up.

How can I log into my actual pocket account to see my saved articles?

My default search engine was Norton Safe Search but now it does not appear as one of the options to choose. I cannot remember all of them. Bing and Google are two of them but not Norton Safe Search although I have been able to add it to the toolbar. Why is it no longer one of the options?

While hovering over a Youtube video it shows the full video title as "hover text" if the tab is focused. However, if something else, even another Firefox window is focused hovering no longer shows anything. Is there some kind of setting to change that? I figured it could be browser and Youtube specific because Chrome shows it on Youtube even when not focused, but neither browser shows it on Google search for example, but I'm not sure.
