I'm using last release Firefox in a fresh install of Debian 12 with KDE. Trying to personalize colors and get a coherent style, I've installed Firefox Color and it worked fine, except for a few GUI elements.

I solved the scrollbars part with this answer:

https://support.mozilla.org/en-US/questions/1419353

Is there a similar setting for the menus? I mean in Firefox's menu bar or the ones popping over the page. The dropdown of the burguer menu and the bookmarks toolbar do get styled (I will include images showing the difference).

Thank you in advance and to zeroknight for sharing the bit about scrollbars!

Hi! I was wondering why nearly every single page these days opens to the message :

"400 Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. Apache Server at canvas.instructure.com Port 80"

Nearly every link I click on a website refuses to open! It has become impossible to do school work on this browser because I can't open any link on my school website, and nearly every website struggles to open except from google. I know the links work because I copy/paste them into Google Chrome and they open immediately. Truth be told I prefer Firefox and would much rather keep using this browser! I also can't find an update for Firefox so I believe my Browser is up to date (and I know my laptop is up to date and virus free). Is there a fix coming soon? Or a setting I can change to be able to open links? Classes start this week and I'm stuck!

Thanks for your help!

I want to be able to start a live stream in Mighty Networks - all seems to work, except the go live button is blanked out. I tried all the usual up to reinstalling firefox and generating a new userprofile in windows 11 and getting a brand new firefox version running in the new userprofile. With other browsers like chrome it just works fine.

On my latptop running windows 10 firefox does not encouter this problem.

Any suggestions are very welcome, I can of course switch browsers but would prefer to see this issue resolved.

Curious to hear if any other users encounter the same issue,

Thanks for any help provided,

Bart

I have a number of contacts where the email address reflects the person's position. Over time the person in this position has changed. Even though I have edited the contact to show the new person's name any incoming email still shows as from the old person.

For example Joe Blogs contact has email director@abc.com We receive lots of email in Thunderbird from Joe. The contact changes so that now Martha Jenkins now uses director@abc.com Now we receive emails from Martha but they still show as coming from Joe Blogs. There does not appear to be anything in the header that refers to Joe Blogs. The header only includes director@abc.com and Thunderbird somehow looks up old email and shows it as coming from Joe Blogs even though this is no longer true.

It is really annoying.

I hope I have explained this well enough.

I was having trouble switching and logging out of Twitter so I thought I could just clear site cookies to make it work, but I weirdly discovered "about:preferences -> Manage Data -> Remove Selected / Remove All Shown" has no effect. i.e. after clearing, when I open up manage data again, they are still there. I did not try "Clear Data" above it because I was afraid of clearing out all my logins.

I reinstalled my computer several weeks ago and current profile was directly copied from my last machine, so this might be a possible cause? Could someone be so kind to help me get remove cookies and hopefully twitter back to work? Thank you in advance.

How do I stop emails from being deleted from Thunderbird when I delete them from my ISPs server? There must be a connection or sync that can be broken but I can't find anything.

Update to version 96 64-bit just completed. Many websites now experiencing Secure Connection Failed PR_END_OF_FILE_ERROR. Did Help -> More Troubleshooting Information -> Refresh Firefox to go back to all defaults. Open Firefox again, add Menu Bar. Open what used to be home screen tabs, ok at first, but within minutes start experiencing Secure Connection Failed in several websites. Seems to come and go, sometimes a Reload current page restores normal website, sometimes not. Close Firefox, open again, restore previous session tabs, only a matter to time before one or more start getting Secure Connection Failed errors. No extensions, no themes. Browser is now so unreliable as to be unusable. Please assist.

I was having trouble receiving emails and I couldn't work out the problem. I deleted my mail account and re-added it. Now all my folders are gone. I can see them in my profile, but can't work out how to get them back into Thunderbird mail. Please help

Hi,

Most of the email folders I exported from MS Outlook 2007 (using MailStore) appeared correctly in Thunderbird, but some folders have no emails in them. When I look at the profile, these folders do not have a corresponding .msf file, which I gather is the Thunderbird indexing file. I have tried exporting these folders separately, but that doesn't seem to work at all; no new profile seems to be created so nothing gets updated in Thunderbird. I have attached a screen shot and can provide others as required. I am a volunteer for Balance & Dizziness Canada and some of the folders I need to export to Thunderbird have a lot of emails and are important for me to have available to refer back to. Many thanks for any help you can provide.

My Thunderbird updated itself to 115.4.1 2 weeks ago. It was a total mess but I've managed to get it all working fine except I used to have An Inbox for all 5 email accounts which stood at the very top of the folder and accounts list. There is no such Inbox there now.

I have 5 email accounts which, in the previous version before the update, all showed in the what you call Unified Inbox. When I go to View and then Folders and tick the Unified Folders it gets unchecked the moment I close the option down.

I've looked at various solutions on this forum but cannot find anything that seems to work for me. I'm faily savvy with programing and computers but this one has me stumped.

I've loved Thunderbird as I've had it some years but I want to get my love for it back :-)

How do I adjust the spacing so that the squares show in full on the side? I tried grabbing the darker gray bar, but that doesn't work.

So what have they changed it to? Cause that is irritating.

Thank you.

I have recentkly submitted questions about issues regarding the menu font size I am experiencing after installing SuperNova, so much so that its affecting my ability to access events on my calendar. I just tested toi see if this was also the situation on my laptops and I found it is not. I uninstalled and reinstalled SuperNova on my PC and continue to experience the same issue. What could be the issue on my PC that is causing this oversized font. It is only happening with SuperNova and not on any other application.

Hi, I've had this problem two other times with various upgrades, where my setting no longer works. I need horizontal lines between message headers in all folders. My eyes need the lines to be able to scan across and not get lost. I am using TB v115.3.3 on Windows 11 Home.

Here is an old version of my problem: https://support.mozilla.org/en-US/questions/1277758

Here is the full content of my userChrome.css file that is located here: C:\Users\Victoria\AppData\Roaming\Thunderbird\Profiles\hid4pw25.default\chrome

@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);

/* Add bottom border to thread pane (message list) */

1. threadTree treechildren::-moz-tree-row {

 border-bottom: 1px solid grey !important;

}

Thank you for any help.

Hello, I recently tried to create an account to sync everything in firefox on my phone, but after a few attempts the account page just wouldn't load, so I decided to update the app because it was quite some time ago since I last updated it.

But right after the update, everything's gone: bookmarks, history, tabs. I was brought to a getting started page like I never installed firefox. I checked the bookmarks/history options but nothing was there. Shouldn't the app preserve its existing data even after an update? Any help will be greatly appreciated. Thanks.
