I uninstalled Firefox on my computer and reinstalled it, but when I logged in, the account couldn’t sync, it was as if the sync couldn’t retrieve any data from the server. Nothing happened at all.

On my Android phone, the data is still there, but when I tap “Synchronize now,” nothing happens either. I’ve tried signing out and signing back in multiple times, but still nothing works.

I also tried switching to a different computer and a different internet connection, but it still didn’t work.

What should I do now?

I wanted to open firefox and a new window for new firefox open but did not suggest me to sync my old bookmarks. instead it only asked me if i wanted to sync with chrome browser only. why was i not allowed to save old bookmarks before new firefox updated.

I have a firefox account that I use for work, which was created with my personal email address - "email"@"personalDomain".co.uk. When I try to log in using it I get a message saying that "personalDomain.co.uk" is not a valid email address. How can I log into my account which was created using this email address? The email address is valid and active, and I do have access to it.

I tried to use a ftp link setting firefox as the default ftp app, not realizing firefox no longer supports ftp. I am unable to reset the default app and can't find the setting to do so. I downloaded filezilla and wish to set it to be the default app for ftp. Can someone help me with this? Before anyone suggests it, resetting firefox to default settings is not an option.

Getting a weird issue. When I open Firefox Beta, if it is not already running it loses focus on Firefox and pops open the Google Play Store over the top of Firefox on its Firefox Beta page. It's doing this consistently and repeatably. I'm on a Samsung Galaxy A52 5G on the latest update of Android 14.

Good morning, I'm running Firefox Developer Edition 143.0b6 on Linux Mint 22.1. A couple of weeks ago I noticed that when moving tabs on the left-hand side they'll instantly get locked into an inscrutable and seemingly impossible to fix "pinned mode". Is there a way to turn this off? It is driving me crazy. I've looked through Settings > General > Tabs and about:config and didn't see anything relevant. If anyone has run into this or knows a workaround, I’d be grateful to hear it.

Recently the email composing function has ceased working in Thunderbird (ver 65.0b3 (32-bit)). Other functionality also recently changed ie clicking the get messages button no longer downloads new messages so we now have to select Get all new messages from the drop down arrow attached to that button. We are only able to type in the email body text area when replying to messages but not when we compose a new message from scratch. The compose new message screen allows us to put in send from and send to as well as type a subject line but doesn't allow us to click in the body text area. If I update the subject line and then tab to try and get to cursor to move to the body text area, all that happens is a dotted line border shows around the body text frame box. I have tried safe mode without addins and removed silverlight but nothing has changed. My wife said she accepted some update a few weeks ago but can't remember what it was for. I will attach a screen shot of the compose page to assist in helping resolve this issue. Thanks

Does anyone know how to highlight in the 65.0beta version of Thunderbird?

I can change the color of text and the whole pages background color but I can't highlight specific text only. I searched for an add on and had no luck. All the add on's I could find stated that they are not compatible with the 65.0beta version.

I frequently highlight text in email correspondence. I can do this in Microsoft word and every other email application I have used. I am resorting to saving my email in Thunderbird and opening it up in my old email application to highlight and then send the email. It's really annoying!

Problems since Thunderbird updated (automatically?) to beta version (63.0). Unable to send from one of my two companies' accounts, despite having been in ongoing communication with their tech support (STARTMAIL) that my settings are correct. They were correct. But now "Account Settings" are not visible (just a tiny non-functional window) unless I got to Help > Troubleshooting Information where they are merely viewable (see below).

Finally, I uninstalled Thunderbird via control panel on my Windows OS. Then I downloaded (from Mozilla website) Thunderbird version 60.2.1.

It opened with the same issues--unable to send via one account; unable to view under "account settings" the details for any of my accounts. Verified with my optimization software (System Mechanic) that 60.2.1 was the only visibly remaining Thunderbird artifact. Did hard shutdown of computer. No change upon re-starting computer.

I had expected that uninstalling and downloading the prior version of Thunderbird would mean that I would have to go through registering in Thunderbird my various email accounts. I thought that I could do this cleanly (all w. IMAP) & more efficiently (no duplicates or leftovers--seven accts on 1 server; one acct on other server). However, Thunderbird opened already populated exactly as I had it (even open tabs) prior to uninstalling.

The only tweaking I have done this week since Thunderbird updated to beta version were: re-set my Master Password... attempt to change the accounts on one server (my ISP's) from POP3 to IMAP (which doesn't appear to have stuck as IMAP, despite speaking to their tech support), but those accounts appear to be working... deleting and re-instating 3x my email accounts with the other server (which is IMAP) due to the problem of not being able to send email's (I have been in ongoing contact with their tech support)--each time applying the new password provided by my server.

BTW, earlier in this process I contacted my antivirus tech support. And I've tried sending with my antivirusware shut off, but login to the server still failed.

Help, please!

I have researched endless options how to download an add on for google search in the options dropdown menu for search engines.

The download https://addons.mozilla.org/en-US/thunderbird/addon/google-search-for-thunderbi/?src=search says it is not compatible with my version of thunderbird which is 60 Beta. What must I do?

I wanted to try thunderbird 60 (60.0b6). Fresh install with a new profil.

And I can't find the "quick reply" option (the quick reply field that allow to quick reply to an email, like in the regular version of thunderbird 52.8).

How do I turn that on ?

Thank you.

I'm running on the beta channel on one machine and release channel on another. The release numbers are far different. Does that mean that what I'm seeing in beta is years away from release?
