What version of Firefox actually allows you to add extensions? I'm running the most current version of Tumbleweed that ships with 144.0. Attempts to add extensions just sit there doing nothing until I close the tab. This sort of worked some time ago (I forget the version) but the inability of Firefox to allow add-ons/extensions is getting to be a joke. There are other browsers out there, ya know.

I can no longer send messages through the email client on one of my accounts using Thunderbird, which no longer recognizes my internet service provider's password (but it does receive messages). Everything works fine with my other accounts.

Thank you for your help.

Occasionally (it already happened three times today) when i'm browsing and switching between tabs, one tab will become an image of its contents (as in - no links work, can't scroll vertically or horizontally) and the others become grey. Trying to reload the pages or open new ones doesn't work, they never load. Turning the browser off by going to the phone's home menu and closing Firefox in the recent applications view doesn't solve the problem, it only closes any private tabs but the issue persists when opening any new tab or preexisting ones. The only way to fix the problem is by force stopping the app. I've cleared the cache, it didn't solve the problem, and reinstalling seemed to work for a few days but now the problem is back. For reference, my add-ons/extensions are: Ghostery, NoScript and UBlock Origin.

I've been "sending" e-mail from my Android phone for six weeks now. It looks like it's going out, but it never gets outside the domain.

I found the suggestion that I check my SMTP settings, but I used a wizard within TB for Mac so I cannot find the SMTP settings on the phone.

The wizard wasn't very wizard: I don't have the contacts stored within TB or the mail from my computer or anything. All I can do is receive e-mail.

I really need to get this working. My computer has died, and everything is going via the phone, and I only use e-mail for communication, not voice or text. (Long story, please don't argue with me about that.)

I just updated Android again yesterday, and TB should be upgrading automatically, if I have this thing set right.

Update: I have found the SMTP settings. They look correct.

My sister's e-mail is working, so the problem is definitely with my settings somehow.

Does anyone have any ideas? I really want to stick with TB.

Update 2: I found the debugging settings and turned on extra logging, but I can't find the logs themselves. Could someone point me to them?

I also tried the TB beta because it says explicitly that it does POP3, but that didn't seem to help either.

Now that I can edit my question, how do I delete the answers that are actually just updates?

Update 4: A different app works. I'd rather use TB if it can be arranged, though. . . .

Any help would be appreciated!

Thank you!

If I go to the profile folder, exit firefox then copy and paste the folder to a backup location. The attempted backup fails. Something about permissions as I recall. I have tried many things unsuccessfully. Something has changed that does not allow for the backup of profile folders. Adding a backup option to the profile manager would be nice. I noticed some people have found work-arounds but I need a straight-forward procedure for backing up my folders. No work-arounds please, just a simple procedure. May I ask for help with this issue?

At startup of Thunderbird, get error related to Outlook which I do not use. Get message - "UserHasNoMailboxandNoLicenseAssignedError"

How do I get rid of this error, has been present since last esr release and expected it to go away with new release - did not. Do I have to reinstall Thunderbird to clear.

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

Hi everyone - and big thanks in advance for considering my request: I have/ had windows 11 on my old machine and windows 11 on my new machine; because my 'old computer' is not running anymore at all (liquid damage), I can no longer start Thunderbird and follow the 'export tool function' (https://support.mozilla.org/en-US/kb/thunderbird-export) and thus can only do the manual transfer (https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer); I didn't think that I would need to go through the export tool steps when I saved the Thunderbird profile folder regularly as backup on the cloud; yet when I started Thunderbird on my new machine following the above steps by moving the Thunderbird profile folder manually, the result is that - although Thunderbird is 'running' and the mailbox is functioning properly - the key folders are empty (i.e. the sub-folder structure is completely lost, in fact there are no individual emails at all); the issue seems to be that the size of the Thunderbird profile folder is too large (the "Profiles" folder has a size of 20.5 GB) for doing this transfer via copy & paste of the Thunderbird profile folder from the cloud (I also tried USB) to the new machine; I understand that the size issue via the manual transfer could be 'overcome' just by starting Thunderbird on the 'old machine' and following the above steps explained under mozilla support; yet that's no longer an option; what could I do please?

I am having severe problems downloading and syncing my emails with TB 142.0. I opened TB this morning, for example, and it took more than 20 minutes for it to download my emails. When I go to the next email, it takes a couple of minutes to load it. I have had some issues with slow syncing before, but this is very bad. I note that the emails work fine on my phone. Also, this happens on my main Gmail hosted account, but also on my other Siteground hosted accounts. TB seems to be lost in some kind of loop when syncing.

Maybe a red herring: I was in the middle of doing a Documents folder backup when I decided to open Thunderbird for some reason. Got an Unable to Load Profile type of message. And my attempts at a fix seem to just send me further down a rabbit hole. I started out by renaming my profile.ini file, but I really didn't know what the heck I was doing and possibly caused more harm than good. Then I tried to find my profile file/folder itself, using the Thunderbird > Troubleshooting > Profile Folder path and doing an import from inside TBird but that ended up with various problems such as drilling down to the profile folder from within TBird but then when I clicked Select Folder in Thunderbird, that didn't trigger any sort of import.

I also spent a good deal of time trying to find my AppData folder, finally being able to view it (a hidden folder, apparently), and saw several recently-dated profile types of folders, but again, I couldn't manage to "hook up" any of those folder/files from starting inside TBird and selecting Import... I ended up just stuck inside a folder, not triggering any Importing activity.

Finally I found a profile folder (5yed...) at a higher level on my PC than inside that long AppData Roaming Thunderbird path. THIS profile was inside: D:\DOCS\Thunderbird\Profiles

Now THAT folder I managed to get an Import to trigger. But the result was an Error Message telling me to go find my Error Console. Can you please see the attached Error Code display screengrab and tell me there's hope that this was at least the right file but just poor results that I can fix somehow???

The following is my copy/paste of the text I see in the Error Console display that's in my screengrab after trying to import the above 5yed... profile, in case it helps you see it better:

Also attached below are also:

• a screengrab of a set of profiles I found, but when I drilled down to them from within TBird's Import selections and clicked Select Folder, as far as I got was an open folder, or something like that.
• Thunderbird's Troubleshooting Info "Profile Folder" path.
• Message telling me to see the Error Console. The message appeared right after I tried importing the profile that's stated in TBird's Troubleshooting Info "Profile Folder" path.

Here's the copy/paste of the Error Console message display after my try at importing the profile that is in the path that TBird's Troubleshooting Info page "Profile Folder" states (maybe it's the same as my 5yed...profile import try's Error Console display, dunno:

Thanks for any help in getting through this.

Recently I have noticed some changes in the way my Thunderbird downloads POP3 messages. Previously, it would be common to ask for new messages once a day and receive upwards of one hundred of them. But in the last month, this number has been limited to about 35 at a time. If I ask immediately again, I get about 35 more, and this pattern continues as long as there are messages in queue waiting to be downloaded. I am not sure if this is due to changes in gmail, where most of my received messages originate, or to changes in Thunderbird itself, or to some sort of third-party hack. Now that I have trained myself to keep on asking until there are no more messages coming down, this change does not cause me much difficulty, although initially it sometimes caused me to overlook messages because I failed to keep asking as long as I should have. Apart from that, it does not seem to be harmful as far as I can tell. I'd just like to know if other people have noticed anything similar, and if anyone knows what is causing it, and whether it has some hidden advantages over the way things used to work.

Firefox used to have my background colors, and on the latest update, my pull-down menu and tabs are robin's-egg blue. I can't figure out how to get my colors back, and I hate that color.

How the hell do I get back control over my colors?

Is there a way to shorten the toast message for closing a tab? I believe it's longer than 5 seconds (I slow counted to 7), which seems excessive.

My (personal, sure) reason for asking is that my RSS reader's "next" button is immediately beneath the toast, so if I've opened and closed an article I have to wait 5 seconds to get to the next.

My manual workaround has been to just leave tabs open and close them en masse, but that's a bit risky, given other tabs I'd like to keep open.

The message in referencing is at the bottom of the screenshot I've attached.

It would be ideal if I could turn them off entirely: I know that I closed a tab, after all?

Thanks at least for listening!

I've been using Thunderbird for years (Windows 11 PC), and all has been working fine as recently as last night. Starting this morning, I continuously get the error message, "Login to server mail.comcast.net with user name xxx failed" (xxx not my actual account name). I've tried the "Retry" and "Enter New Password" options to no avail. I can go directly to the Comcast website, login and get my email that way, but I can't get Thunderbird to login.

To my knowledge, nothing changed between last night and today, but yet something seems to have happened. Any ideas appreciated!

Certain PDFs only allow page view when opened in Firefox. When opened with other PDF viewing software or browsers (Microsoft Edge, Adobe Acrobat, Google Chrome), these PDFs allow continuous scrolling. I don't have this issue for most PDFs.

I've tried fixing the problem by editing the PDF settings in Adobe Acrobat but to no avail. When combining a PDF that works fine with a PDF that doesn't allow continuous scrolling in Firefox, it seems to take on the settings of not allowing continuous scrolling.

Examples (these link to documents from a Florida public document database): Example 1 (made with Power PDF Create) Example 2 (made with Adobe PDF Library): https://depedms.dep.state.fl.us:443/Oculus/servlet/shell?command=getEntity&[guid=5.506115.1]&[profile=Cleanup_Remediation]

Edit: Firefox 145.0.2, Windows 11

Idk how to fix that problep bc its really bugging me out and i am going crazy

Here are the steps that i do to recreate the error

1. open a new tab
2. search up any website
3. on the same tab search up a diffrent website or click on a link on any link that redirects you on that website
4. literally after like 3 seconds firefox redirects you to the site that you were on before

Please how do i fix this cuz I hate it so much plskdjdiehzuzgzuahzjzvzkuzjzvz

I have this new issue, that Firefox needs like 3-4 seconds, before loading a page. It stays blank until then. Why has the Performance decreased so much?

Reinstall didnt help
