Long time Firefox user here - been on from the start (about 2005), and don't want to switch because I love some features like the Panorama View extension, Context Search extension etc, and it's always been a great browser.

Recently though (not sure if it's just recently, or I've only just noticed), it's so slow. I tried a brand new profile, no extensions, no settings changes, and it's the same. Example loading times:

bbc.co.uk/news Firefox: 14s Edge: 2s chess.com Firefox: 19s Edge: 4s chess.com play vs computer Firefox 38s Edge 2s

https://youtu.be/er9jBysL0vEFirefox vs Edge (YouTube)

So it's not my profile settings or extensions.

BUT, I tried it on a different user profile on the same computer (Switch User from the Windows Start menu), and it's fast!

Why is this, and what do I need to do on my user account to speed Firefox up (keeping my same Firefox profile)?

Thanks in advance.

Pretty much title.

Since about two weeks when I open firefox the browser freezes every few minutes for 10-15 seconds. Launching firefox in Safe Mode or disabling all extensions didn't help. When I open Task Manager during freezes it shows that Firefox is "Not responding" and when I open sub-tasks it's usually one or two causing the problem. When I close those either firefox closes completely or youtube or reddit crashes, leading me to believe it's something with those sites? Refreshing or reinstalling firefox hasn't helped. I'm on Windows 10 (all updates installed) and Firefox 84.0.1 (x64) as of the time writing this.

I hope someone can help and suggest something. I would hate to switch to another browser, but the problem has become unbearable.

Thunderbird has become dysfunctional, I think since the last update. I’ve been using Thunderbird for many years, with an Earthlink account, set to POP3 server. Currently, I am using it on my iMac with Mojave 10.14.6. The first symptom that I encountered was being unable to Send emails. Then, I discovered that I couldn’t download emails. Later, to my surprise, it downloaded the latest emails from Earthlink, but all of that email was still on the Earthlink server.

I changed the Earthlink password because I was afraid it was defaulting to IMAP, which I don’t want. But I haven't been able to enter the new password in Thunderbird. I can hardly do anything without getting the spinning ball, and the application freezing. I have to Force Quit to try again, but the same thing happens. Furthermore, I have discovered that the Earthlink account is duplicated under Account Settings. I have absolutely no clue how that happened!

Loading the program and selecting About Thunderbird brings up nothing, so I can’t tell you the version I am using. The Earthlink account is not my only account in Thunderbird. If I have to reinstall the application, would I have to set up all of those accounts all over again?

I have archived emails going back to 1998, when I used Netscape. Most under Local, but some in the Earthlink account that I was using for downloading emails. Yes, my Thunderbird library (libraries?) is/are backed up. But I’m afraid to delete things from within Thunderbird.

Whenever I move an e-mail message in Thunderbird from my Inbox (which is IMAP) to a local folder, the Firefox Web browser immediately opens up with the next message from my Inbox loaded in it. I've been using Thunderbird and Firefox for many years, but this problem just started recently. (In case it helps: If I move an e-mail from the Inbox to another IMAP folder, there's no problem. It's only when I move it to a local folder.)

Topic - How to reduce the GB size of the Profiles folder? Using V 78.7.1 I have backed up my Profiles Then I deleted several files and folders with no activity for several years. Then I deleted older emails in several other files. The amount of time that I want to keep emails varies based upon which file folder I use to save the email. (I have 45,000 saved emails, and I don't plan to have more than 70,000 saved emails before I purge older emails.) Then, in the Profiles folder, 566jlfn3.default, Mail folder, inbound.xxx.xxx file, I deleted the folders that I had deleted in the program, and I deleted the MSF File and other File with the same name. (I did this both in the Roaming folder and the Local folder.) Thunderbird still works fine. However the size of the 566jlfn3.default in both the Roaming folder and the Local folder remained about the same size, 17 GB. (This file used to be less than 10 GB.) I was hoping to reduce the size of that file. I want a smaller 566jlfn3.default folder because I move that folder to different computers when I am in different locations. Can somebody please help me find the files that are using the GBs? [I posted this by mistake as a reply to another user's inquiry that appeared to address a similar issue. Sorry]

Hi,

I'm trying to disable the media popup in windows 10, which appears when you lower your volume or skip a song or anything (see added image). I have a brand new pc and on my old pc i was able to fix this easily by doing this: go to about:config and change this: set media.hardwaremediakeys.enabled from true to false.

I did that now, with my new pc as well. But i just does not work, i restarted my browser and pc after changing it, i set it back to true and back to false again, it just will not work.

I googled this issue, but the only solution i find, is what i exactly the thing i described above, nothing else.

I have had Firefox downloaded for a considerable amount of time and had begun to use it as my daily browser, until I started experiencing issues, concerning the loading. I have experienced this issue in all cases when trying to open the browser through the desktop shortcut, other icons, and even the .exe file, and typically I will see a brief white screen of Firefox before it immediately closes again. Frustrating to say the least and a quick google provides no insight. I have attempted on multiple occasions to uninstall and reinstall, however to no avail, and have even tried to create a new profile, via the Run (Firefox.exe -P) but again with no success. Running the browser in Safe Mode (Shift) will also work for a split second with the dialogue opening and then instantly shutting. Any suggestion on a potential fix would be great.

Hello,

I have synchronized a shared Google calendar via https://apidata.googleusercontent.com/caldav/v2/xxxxxxxxxxxxxxxxxxxxxxxxxxxx@group.calendar.google.com/events in Thunderbird. This basically works fine.

But if there is a recurring event (e.g. every two weeks on Wednesday) and someone moves a single one of those events e.g. from Wednesday to Thursday via her/his Google Calendar app on Android smartphone, this single event will still show in Thunderbird on Wednesday instead of Thursday. While it shows on Thursday in Google Calender app or on calendar.google.com (see Screenshots).

What can be done to show the event on the correct date in Thunderbird calendar, too?

(This is no synchronization problem, other events added later are shown in Thunderbird.)

Many thanks for your help!

I find it really bad, if i post a bug and you just archive without even try to fix the problem! It makes me extremely angry! Bad behavior!

Please stop that and re-open the case.

Jan Ps. same system (Lenovo Thinkpad X300 with Xubuntu 16.04LTS 64bit (account A) )now running Firefox 85.0.1 64bit can now print, I can't find any mentioning in release notes to how previous version 75.0 and now this one is different and why this one now can print.

It would be nice to get this solved, since other people here has had this one too and it seems to jump between versions and OS(linux an windows).

I have just migrated my caldav calendar from synology webdav server app to the synology calendar app. No problems connecting and synchronizing, other than each time I snooze a calendar entry a new alert is added to the calendar entry. For example, the calendar event is created with 1 alert 15 min before the event; after I snooze the event the first time in Thunderbird the calendar event is updated then shows two reminders 15 min before the event, the second time it is snoozed then four reminders appear, etc. I'm not sure whether this is an issue on the Tbird side, or the Synology App side. Didn't have this problem when running it through the webdav server app. Nor does it appear to be a problem with old recurring calendar entries that were imported when I imported the calendar; it only seems to happen on new calendar entries. Anyone experience the same issue?

Lately I've been repeatedly asked for my SMTP password on the first email I send of the day (until closing TB) from certain accounts of those I have.

There appears to be nowhere where I can just ADD an SMTP account and it's respective password.

The particular accou8nt does not appear in the SMTP list of about ten accounts I have. Thus I can't edit it.

Believe me, for the two accounts in which this has been happening, they were once in that list.

Now the account is there but the smtp usage data is not on a line.

And when I do enter the respective password, TB does not ask me to remember it nor make an addition to the SMTP list.
