Hi, I have used Thunderbird for many years and always liked it. I would like to know is there a way to tone down the brightness of the white message pane in email ?? It is very bright and glaring. Any white anywhere else I go is just fine. Thank You,, Banyarola

I normally open messages in tabs under exactly one circumstance: when I right-click on a message and explicitly open it in a tab.

I've found that (until I changed the handling of PDFs to "Save file") any PDFs that opened using Thunderbird's preview function would reopen if I closed and relaunched Thunderbird. This is not desired behavior.

I will also note that if I open Settings, it opens in a tab, rather than a separate window. This is neither expected nor desired (and my natural reaction is to click the close button on the window, closing Thunderbird, because "Settings" is something I expect to be in a window, not a tab. And that, too, reopens if I reopen Thunderbird.

And worst of all, those tabs that shouldn't be reopening at all are reopening in front of the main tab.

There was an extension called "Thunderbird-DontRestoreTabs," that would do exactly what I want, but that was made obsolete when the underlying extension technology was deprecated, so it is of no use in 115.9.0.

how can i stop thunderbird from interacting with windows defender anti virus scan? when ever i download or delete emails i get a few seconds of "not responding " and the whole computer is non responsive. i used to be able to turn off real time scan in security and it would work for a day and then windows would enable it again. now since the last upgrade windows isnt allowing me that option any more. solutions?

I have two end users that are having a different issues but they are of similar nature. First user can not upload anything to Microsoft Share point. She gets a message that says she does not have proper permissions to upload. She does not have the same issue on Chrome or Edge. The second user is trying to download and or save a file from a couple of different websites but regardless on where she tries to save it on her computer it says she does not have proper permissions to save to "x" file location. She also does not have this issue when she is on Chrome or Edge.

For both users I have tried clearing cache and cookies, Rebooting their computers, uninstalling and reinstalling Firefox, deleting registry keys/user data from the computer itself. I have had no luck with resolving this issue and I can not find anything online that remotely resembles this issue.

Thank you and please advise

Sorry, posted recently and had then trouble finding out how to respond to help offered (jscher2000)! Noticed that the email version was "no-reply" so I didn't figure that would work! So, I tried to 'cut and paste' my reply (on a smartphone) and I ended up losing even the email reply text so here is a reconstruction. I tried the suggestions in order and the first one didn't have a "Restore previous session" option and the second one had "Recently closed windows" greyed out! And, when I entered "about.support" in the address bar (top rightish), I received a notice that I couldn't reach Google (Remember that I don't currently have internet access on my laptop). So, no joy there either! Can I not just change some current setting to prevent Firefox v 115.9lesr from saving the current 'Windows' and Tabs so that, when I again open Firefox, the previous session 'Windows' and Tabs would be used?!?

Hi, I would like to implement GPO settings for Firefox, and would like to review the list of the policies with description (explanation of what the policy is about and what happens if its enabled or disabled) on a table or excel format. Is there a site or page that will give me that list?

It is annoying that search executes immediately instead of triggering on enter keypress, especially when a web page is big. Is there any way to disable auto-search and trigger it only when you press enter?

If you want to understand better it's pretty similar to this VS Code issue.

I get the following message when going online with Firefox: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I've followed all the prompts to restart the computer, refresh the computer, delete the favicons.sqlite and places.sqlite and it won't allow me to delete them. This happened yesterday as well. Yesterday I could delete those files and everything was restored. But today I can't get it to work.

I have to put my face within inches of the screen and strain to see the text in Firefox browser menus, tabs, and search bars. How do I adjust the font size?

I'm not a programmer. If I need to enter code please be pedantic about descriptions of how to do that.

I have been using three email accounts on Thunderbird, all for a long period of time, and all without any issue. Recently the one listed below has not been backing up, and I receive this message. I am not techie at all, so any response needs to be dummy down to a 5th grader level. Thanks!

"Non-overridable TLS error occurred. Handshake error probably the TLS version or certificate used by server mail.q.com is incompatible."

I am writing to report an issue I have encountered while using the Firefox browser. Specifically, I am unable to take screenshots on the website https://hescoebill.pk/hesco-mis/. This issue persists despite numerous attempts, and it seems to be unique to this particular website. Is there any other way to take screenshot of site? I really want to take a screenshot for personal reason. Is it not allowed from the site owner side or what?

I currently have a 'bad/rouge' session of Windows 7 Firefox (don't really know how that happened) open (7 'Windows', each with one empty Tab plus 1 'Window', with only 1 populated tab (Yahoo Mail)! I need to close Firefox in order to restart my laptop (strange things have been happening, including not being able to access the internet)!! On restarting, I want to be able to open Firefox with the previous session I had with my 8 'Windows', each with dozens and dozens of Tabs! Please help, I sorely need those many 'Windows' and Tabs!!!

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at all. I am at a bit of a loss, any ideas?

A while ago, I had to work offline so I had TB download my Gmail account messages. Now I no longer want these messages to be stored locally, because the Thunderbird folder is up to 10Gb, so I unchecked the box in Synchronization for 'Keep messages in all folders for this account on this computer'. I was hoping the TB would subsequently purge the offline folders, but apparently not. Is there a way to clean out the folders without affecting my online Gmail folders as in Inbox and Sent folders?
