Firefox Community Forum

Hello there, Iam facing a problem with changing Firefox homepage background. I tried every solution, tutorial, oldposts etc. nothing seems to work, here is what I tried. -1- The chrome folder is in the right folder. -2- the naming of both CSS files userChrome, userContent. -3- enabled CSS files at startup -4- search for both CSS files in the browser toolbox for some reason I cannot find both CSS files, even though they are in the chrome directory. Also, I have 2 chrome folders one of them is located here. "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\storage\permanent\chrome" the other one I created myself which is here "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\chrome" I tried to delete the first one but I cant, I get an error that this file is being used even though I did close Firefox. What I am missing here?

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?

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.

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)

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?

Today I tried using a Socks5 proxy that requires user and password. It seems that this is still unsupported as already concluded in https://support.mozilla.org/en-US/questions/1237174 and https://bugzilla.mozilla.org/show_bug.cgi?id=122752

Any news on this?

Kind regards,

aanno

PS: I _was_ able to use the very same proxy with curl with

curl --proxy-user user1:pass1 --socks5 "http://localhost:1080" https://www.google.de

You may have heard about this, Youtube (and parent Google) have recently declared war on adblockers and non-Chrome browsers. I have reason to believe they have escalated that war to deliberately crash non-Chrome browsers, at least slowing them down to make them non-responsive.

In the past few days, browsing Youtube has caused my system to stop responding requiring a power cycle to clear the problem.

Has anyone else encountered this problem? Is this just a bad setting, or is Youtube acting as malicious as I believe them to be?

Hello, I'm using Firefox as my default browser for a while now (10+ years) and I'm getting frustrated with this issue when using Azure Devops. Comments don't load at all and most pages take a long time to load if they load at all. Various features also take a long time to load or don't work at all (examples include adding a reviewer, referencing a story with #, etc.). Anyone else experience this?

It works well for maybe an hour, and after a couple of days it makes no sense anymore.

Now I'm using firefox containers with a container only for Azure Devops and seems working better but ... Curious thing is that it pops up and asks for credentials periodically every 5 or 10 minutes. Well, unless the boxes are already filled up with the credentials.

Thanks,

I use several add-ons in firefox, and largely they feel trustworthy, but I dont have any means for limiting the scope of what they are able to do, the manifest tells me what they can do and thats it. I have read through this page https://support.mozilla.org/en-US/kb/permission-request-messages-firefox-extensions, but I have had a hard time even understanding which permissions let an add-on make network requests.

Barring the ability to actually stop add-ons from making network requests is there any visibility into what requests are being made by an extension, or all extensions in the browser?
