I am using Firefox v125.0.2. When I open a PDF in Firefox it takes a lot of time to load. But, when the same PDF opened in the Edge browser it loads normally and scrolling through PDF pages renders fast. I have shared the screenshot of a single-page pdf loading taking quite a long time.

Could someone please help me with this.

I wouldn't have to do this except that somehow, a Bookmark folder disappeared. All too often is has occurred. I have many, many very important Bookmarks. How can I get them back---and soon?

Hallo, Ik gebruik 2 verschillende gmail-adressen in Thunderbird. Met het ene adres heb ik geen probleem, met het andere krijg ik steeds de melding "Authentificatiefout tijdens het verbinden met server imap.gmail.com". De serverinstellingen in de accountinstellingen in beide adressen zijn identiek. Hoe los ik dit op? Bedankt voor uw reactie.

Hello everyone,

I started using firefox actively a year back or something like that, last couple of months it started driving me nuts as it started updating every time I launch it, which is very annoying even if it takes only 10 15 seconds, I sometimes need to check something really quick and I have to wait for it to finish installing an update, even though I checked the setting for it to do so in the background, it seems to only do it after I launch it disrupting my workflow, which made me switch back to Chrome temporarily, is there a way to fix this?

""Description: COX Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication method: OAuth2 User Name: your user name, duh - Mine keeps changing the user name to the last name I put into any of my 6 accounts. The only way it will send mail is if the correct user name is in the correct account (obviously). Why is it changing constantly? click OK""

I've read the "fixes" from 2023 and they do not work for me. I tried changing the DESCRIPTION to blank, didn't work. Changed them to the corresponding e-mail for the account. Didn't work. Changed it to "SMTP" with the corresponding e-mail. Didn't work.

It keeps changing the last one I edit to the one I edited before it. It's driving me crazy. Won't send mail unless the User Name is correct (obv.)

Whole mess started when forced to switch from Cox to Yahoo recently. Seems to be working other than TB changing the name as soon as I type in the next one in the next email address and then it not working until I change the User Name back to the proper e-mail address of the 6 accounts.

bold text4 or 5 years ago i simply synced TB and Firefox straight to my laptop from my desktop. Today it does not seem to work that way. Why has it gotten more complicated? I have all of my emails, address's and etc.saved profile and cannot seem to replace it. I tried the thunderbird.exe -p and it gets confusing there. Apparently it does not give one the option to replace profile like mine, but one can create one. I tried creating by entering my old Profile and it did not work. It says to use the Browse button which should bring you to the actual spot to add your profile. I do not see a 'Browser" button, but do see 2 separate folders buttons, but i do not know which to choose, if any. I have donated in the past when things were working smoothly, but discourged to add to it now with all these upgrade mess's. Like they say, "if it ain't broken, leave it alone..." s amd

I recently purchased a new laptop and needed to migrate my old Thunderbird profiles. This is what I did: 1. Backed up profiles from old laptop 2. downloaded and installed latest version of Thunderbird on new laptop 3. coped profiles into \roaming directory 4. tested and successfully received emails and viewed all old emails.

The problem is that the Mail toolbar is nowhere to be found. Also, the calendar is missing. I tried right clicking on empty space and it only showed "menu bar" as an option. Attachment shows nothing in the toolbars option of View dropdown.

Got up this morning and FF said all my tabs were crashed - GAH! Could not open ANY new tabs, not even a blank tab, without getting this message. Clicking on restore tabs did nothing. Closing & opening FF did nothing. Cleared startup cache & uninstalled ublock origin (the only extension I had) but that did nothing. Refresh firefox did nothing (except lose some of my preferences). Went to about:crashes and all it says is "No crash reports have been submitted." Every other suggestion I found online was beyond my comprehension. FF DOES work in troubleshooting mode only, but I lose some important functions in that mode. I've been using FF almost since it was born and have NEVER encountered a problem like this before. I hope someone can help!

Start new Windows session. Start Thunderbird and works OK. Shut Thunderbird down and try to re-start during same Windows session and it will not launch. Reboot Windows and try to start Thunderbird and works OK. Alternatively, going into Task Manager there will be a number of Thunderbird processes running. If I manually end them all (while Thunderbird is NOT active) then I can restart as normal too. This all began with 124.0 Beta 1. Never had the issue prior.

Also, Thunderbird crashes if restarting within the app. By this I mean clicking the X it appears to close (excepting those persistent processes running) but "Restart Thunderbird" such as to launch Troubleshooting mode or from the "Restart to update Thunderbird" config crashes the app with 100% consistency.

I am a longtime Thunderbird user, currently running 115.6.0 (32-bit). Very recently Windows Defender is detecting malware it identifies as Trojan:HTML/Phish!pz. Defender is unable to quarantine or eliminate the threat.

The specific file is appearing in Volume Shadow Copy data when I am running backup: file: \Device\HarddiskVolumeShadowCopy55\Users\fhanz\AppData\Local\Thunderbird\Profiles\sootdszw.default-release\cache2\entries\342F92977A0BA0715CB8880A9289BC8F8827262C

I've attempted several times to remove the offending file(s), but the problem returns.

What is the best method to determine the source of this malware and effectively eliminate it returning?

If it matters, I use Chrome as my default browser.
