I am using a windows 10x64bit desktop and I want to find a 32 bit version of Firefox for my laptop which uses Windows 7 x32bit. I have tried the download for customising, ie set it for Win7/8 but the version which is downloaded reflects on the laptop that that version can only be used on a Win 10 computer. Please give me a link where I can find the 32 bit version of Firefox meant for Win 7. THANK YOU.

I have a problem with forwarding messages. This issue only occurs when the message is signed with an S/MIME certificate. Pressing the forward button opens the email forwarding window, but there is no content or attachment in the email. The problem started today after updating to version 128.6.0esr.

I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

I am not getting my email on Thunderbird. I am getting this message: "Could not connect to server pop3.optusnet.com.au; the connection was refused" Could you please help with this? Kind regards, Luke

On the latest Firefox Nightly builds (I use Nightly for extensions), holding the back button in the Android navigation bar no longer brings up previous pages, like it does when holding the back button in the three dot menu. Is there a config option to bring this back?

When attempting to sync my data on my android device it doesn't do anything. I'm currently in the account settings on my phone and when I hit "sync now" it just does nothing.

My email messaging seems to be set at a defined format with double spacing. I prefer to use single spacing but in order to do this I have to type all the way to the end of the page and then it will automatically go to the next paragraph and will then use single spacing. I would really like to be able to format my emails with single spacing and different margins other than what I have to use now (i.e.using the entire width of the message). I cannot find any way to change this automatic double spacing and change the width of the paragraph at the same time. From the drop down list directly above the body of the message, I have tried changing from Body Text to Paragraph and back again, but nothing works. Thanks very much for your help.

P. S. I am using Windows 10 with Thunderbird version 128.4.2 esr. I had the same problem in more recent versions but not in older versions.

Hello, Sorry to disturb but its been two days and I am unable to access my Google accounts (work and private) through Firefox in anyway. I have done all the basic fixes I can think of but with no success. I have deleted caches, checked plug ins, rebooted Firefox went through the trouble shooting mode, followed advice in the community forum, tried logging in from Google linked accounts. Spoke to our internal IT support at work but nothing has solved the issue as yet, spoke to Google support.

My assumption is that it has to be the browser as I am able to log into google with another browser but Firefox is my preferred browser and would like to use it again as such.

Please advise.

Thank you Cait

I'm with Optus,have had TB for many years,always worked perfectly. I made no changes to anything.3 days ago Thunderbird stopped sending or receiving messages. I get message "could not connect to server pop3.optusnet.com.au: the connection was refused". I have 2 email accounts (coghill1@optusnet.com.au and coghill2@optusnet.com.au, logged in via Optus webmail, can send and receive between accounts fine, so I assumed this was a TB fault, but when I reconnected my old Win7 PC (has been offline for months and was working fine) and tried TB, I got exactly the same result. I have previously spent over 3 hours on the phone to Optus tech support when setting up the Win10 desktop as TB didn't want to acknowledge the "myname2" account, got absolutely nowhere with them, clueless, solved by doing backup/restore from Win 7. I'm hesitant to attempt this again as the old system isn't working either. Hope this makes sense. Any help appreciated, thanks in advance. UPDATE: still not working but I've had to install Outlook and it's working perfectly. Thanks for the replies so far.

Since yesterday Thunderbird keeps crasing. I don't even have time to go see if an update was added. It crashes within a few seconds all the time. Any ways to fix it?

For some reason on android firefox I'm no longer able to pull up a tab's history by holding down the back button. I can still press to go back, but there's no way to either go back several pages or to go forward if I have already gone back.

While browsing youtube,i no longer find cast to tv icon in Firefox browser.Can you help me please,as after stroke my eye-sight is diminished.I was able to do it before,as i switched over Linux Mint 22 wilma,i am unable to find this cast icon.Thanks.

Error message: Calendars currently disabled., Enable Calendar. Not intuitive or user friendly. How to enable calendar? Search help, support, no information? Would expect to find in settings, or tools, but not there. Where is the secret hidden?

Since update to ver 128.1.0esr the "new subfolder" feature does not work (does not show window to name new folder). I have many subfolders and I rely on them heavily. I tried restarting Thunderbird, then Windows. I ran in debug mode with no success. I downloaded and installed 128.2.0esr again. No change.

Is it possible to go back to the earlier version? Which is? Thanks, Frederick

Hi !

I'm running Thunderbird 129 (beta) on Win10. Long time user & fan of TB...

Currently, right-clicking on Properties or Compact for any folder won't launch/start anything in my TB. Any clue ? Many thanks !

Bit of context: . I'm running numerous accounts and folders; . here, I wanted to compact some folders to bring some hygiene to my mail boxes; . I've been running huge Inboxes (10ks of emails, Inbox file of several GBs... I know, this is BAD ! sorry...) . some of my folders are starting to show corruption symptoms (dates 1970, rubbish text in preview, nstmp folders...) . my TB is parametered to compact when 200MB are saved (though I doubt it actually does) . I used to have msgs requiring me to compact folders, but don't seem to have them any more (maybe the system got tired with my ignoring it ;)

I have read different threads about Compacting (Complications, workaround, Compacting folders...) and folders, but didn't found any solution/workaround. note: I haven't seen any post reporting this specific issue (right-click menu opens, but functionnalities there -such as Properties or Compact- seem inactive or somehow dis-activated).

I tried disactivating any download, and moved huge nstmp files out of the TB folders (trying to make them somewhat lighter).

Many thanks for your help !
