Im using Thunderbird Beta release. Starting last week, my PC would become extremely slow, to the point it would nearly come to a complete halt. After digging around, I realized it was due to excessively large Thunderbird NSTMP files that were being created. I would delete them and the speed would improve. But then a while later, the NSTMP files reappear and gobble up all my Harddisk again. Part of the issue is the sheer large size of the file, which will consume all available space on my HD, which at present is 600GB. But it also eats up all my RAM so my system slows down til the NSTMP file is fully built.

I use this as imap with Gmail installed on a PC with a 1TB SSD

Today after my pc started slowing again, I started poking around and noticed my main Inbox is massive, 29GB, which there is no chance its that large. All Mail is only 1GB to give perspective

This has been going on about a week.

I tried repairing my inboxes and other folders, but that does not seem to have helped.

Hello, Firefox randomly downloaded a file, with seemingly randomly name, that is 0 bytes and in download manager the source is moz-safe-about. It happened when I was accessing a popular wiki site. I opened the file in notepad, it was empty. I put it on virus total and came back negative, as it is an empty file. I've curbed through the support tickets here, using the keyphrase 'moz-safe-about'. I understand this was/is quite a common problem, but it still makes me quite worried and left a sour taste in my mouth, as I haven't understood any of the explanations. I have enabled firefox to ask me whenever it wants to save something (I have no idea why this isnt the default state). Happened on a somewhat fresh, updated win 11 installation. I'm also attaching more information here with a picture. Long story short: should I be worried? Am I overreacting and this is just some sort of a bug that occurred while getting a sites data? Thank you for your time.

I added a PNG picture as a background to my emails. Instead of a single background picture, it produces a collage (can't think of another word) of multiple copies of the same picture. Any way to just get a single picture?

Created several email mailing lists. Stored them in the Personal Address Book (PAB). I'm sorry, but Thunderbird doesn't seem to work like any other email client. How do I address an email using one of those mailing lists in the PAB. Tried typing the whole name of the mailing list in the To: field. Didn't work. I'm not entirely stupid but it doesn't make sense to me.

Hello, Firefox just released the newest version on PC and advertised it with a speedtest: https://browserbench.org/Speedometer3.0/ I made that test and got a score of 7.03 I made that test on Opera mobile (My phone got locked while the speedtest was running, so this may had impact) and got a score of poorly 2.14 BUT on Mozilla mobile which I can confirm feels SLOW is the speed score: 1.70 And now lesser is not = better. I like that you can arrange tabs, I like that you can use addons, but I miss a scrollbar, I miss side LOADING/OPENING speed. Many many people love Firefox on PC, but why is it that slow on mobile? And why can I not get a button to scroll fast up and down? I have to install a addon which I need to access everytime to click "scroll to top/bottom". That isn't handy!

I really wish, the developers would share some love, because I LOVE firefox, but this is just not useable :( I mean come on, a scrollbar! Give it me! And SPEED. And no my Samsung Galaxy S10+ with 8GB ram isn't too slow.

I don’t understand what Firefox is doing. For example, I used to start typing the first few letters of “weather.com”, which I visit pretty much daily, and it would auto fill “weather.com”. Now it auto fills every time with http://www.weatherbase.com/. I don’t know where that came from. Similarly, I used to type the first few letters of “duckduckgo.com” and it would bring up “duckduckgo.com”. Now it brings up a magnifying glass below the url with “Search with duckduckgo”. I am thinking it might be best if I can start over, i.e. clear out any information it’s saved about where it thinks I want to go, and start remembering the sites I am entering now.

Hi everyone,

I'm running Firefox which I compiled with vaapi support because I was trying to use hardware acceleration for videos, so I think this bug may have something to do with that. Every time I open a pdf file my browser instantly crashes. When I use troubleshoot mode I have no such issue. I then tried with a fresh all-default user profile with no add-ons, nothing, and still I crash when loading a PDF. Any pointers would be appreciated.

Sometimes I find that Firefox just randomly closes on my laptop, usually when I step away for about 10-20 minutes. I can't find any info in the about:crashes page when it happens.

Hello! I updated FLOORP on the 5th May, FLOORP crashed and then Brave, Firefox, Waterfox, LibreWolf and Vivaldi started crashing. I had Brave and Vivaldi open when I launched FLOORP and FLOORP asked consent to update itself and after updating, it did not open in “previous session” and I could not open “previous session” through History. When I launched “Settings” from menu, “previous session” opened! I had pinned “Settings” earlier.

Now the bizarre happens; suddenly LibreWolf launches by itself also without “previous session” and open tabs in Brave and Vivaldi disappear to single New Tab. After some tinkering, I was able to restore “previous session” in LibreWolf, Brave and Vivaldi.

Now I close all browsers and open Firefox, no “previous session” and some random windows in its history, opening these random windows also opened “previous session”! 🙄But then Waterfox launches also without “previous session”, here clicking on OneTab extension recovered “previous session”.

Cutting short; I uninstalled, Waterfox, LibreWolf and FLOORP, this did not help, I ran System Restore twice to two different points and it has not resolved the issue.

Thankful for any help!

My default search engine is Duck Duck Go. I frequently use a VPN.

I am usually in North America and want to search sites in North America. When I run a search by typing a search term in Firefox, I get results beginning in UK, and I see that a blue toggle switch has been set to UK. (See image.)

This started 2-3 weeks ago.

How do I set things so that my searches begin in North America?

I have checked "about:config" preferences and do not see anywhere that UK is specified. I don't see a region preference setting, either.

Thank you.

After accidentally cutting power to my pc, Firefox has been crashing upon start. I've tried using Troubleshoot Mode, refreshing, reinstalling, and even manually deleting all my user data, but nothing has worked. These crashes do not appear in the crash logs, and happen instantly upon opening the program.

Oddly enough, using task manager to restart Windows Explorer stops the crashing, at least for thirty or so seconds (this is how I was able to try Troubleshoot Mode, as well as accessing logs). I have no idea why this is, nor if it's useful information.

I made a private homepage years ago made up entirely of links to web-based AND local folders and files that are grouped into columns of categories like banking, medical, insurance, budget, etc. I keep it off-line on my desktop. I wrote the code so I could place an external link to a bank for example, next to a local link to the folder on my computer where I download statement pdfs from that bank and other bank files. The web page links displays: MY BANK Chkng/Debit Statements Credit Card Statements Bank Information The top link goes to the bank web page on line while the three lower links open folders on my computer where I save pdfs, txt, images, etc from the bank. Firefox opens the folders as "Index of file:///C:(folder path).

My personal home page is laid out with groupings like this for all sorts of information and associated web links: broker, vendor invoices, medical test, taxes, social security, health insurance, subscriptions etc. Today we get .pdf files with all sorts of information and no help organizing it for easy access. The Firefox browser has become the perfect tool for me. But I learned HTML coding years ago! Not so easy to do for others.

Today, many entities have on-line access that provides downloads like invoices, test results, payments, subscriptions, and much more that replace paper. Creating folders to hold these documents with their own local links on your web/local homepage makes sense to me.

While you can use "File" on Firefox to open a local folder or individual file, you cannot save it as a link. However, you can copy the path and transfer that to an a href=" line of link code in your homepage and build on that method. It's amazing how many types of files can be displayed in a browser that are locally stored. Even a link to a spreadsheet file will open that spreadsheets application. Having a varied list of links with quick access is worth the code-writing time. I wish there was an app to help anyone make their own custom folders and links to the contents in a "my homepage.html" . Is there a product idea in there for you folks?

I have reviewed the previous forums on what changes to make to the outgoing stmp for outlook and have implemented them however, I am still unable to send emails. Please see attached for the edit smtp settings I am using. According to the forums these are the correct settings. The only difference is that I don't seem to have the ability to set authentication method to login as that is not an option for me.

What am I missing?

I mistakenly moved a folder into another. It is now a subfolder and I want to move it back. The move command is not working. How do I move a subfolder back to be a primary folder?
