Hi community!
For some reason, the short description of an email is now under the subject instead of besides it in the overview. This does something to my head that, atleast for me, makes it cluttery and hard to hover over who sent me email. I want a column with who sent me mail, then I want right of it a short description, the start of the mail, just like it always was. It takes vertical space so less email is visible and my head has to switch from "from" to "content" to "from" to "content" which is for some reason very tiring. It's one of the reasons I hate outlook... Please don't tell me Thunderbird changed into outlook -_-
How do I change this back to the way it was?

My Firefox now only opens to a partial page size, not full, even though I click to a full page and then close out.
Opening again just goes to a reduced size page.
I have backed up my profile, uninstalled Firefox and reinstalled and brought my profile back in.
Still the same problem.
I think there is a file that controls this that is corrupted.
Need help.

I recently reloaded my M1 MacBook Air with macOS Sequoia. Ever since doing so, Firefox opens the right-click menu every time I press Control+Return (like when attempting to autocomplete a URL ending in .com, a feature I use quite frequently). It is only in Firefox that this happens, no other browser or program is doing this. I have uninstalled Firefox using AppCleaner, downloaded a new copy of Firefox 131.0 and reinstalled without any change in this behavior. Any ideas on what I can do to stop this so Control+Return only autocompletes a URL again?

Hi,\
Over the past week or so, my homepage refreshes intermittently and all of the time when I close tab. When I am on my homepage to read (MSN), I typically use the right click command to open the links in a new tab so I can keep the article in the homepage there. Every time I close the news tabs, the homepage refreshes. If I am just sitting on the homepage for few minutes, it auto-refreshes.
This does not happen on Edge or Chromium and I have been back to Firefox because I want more control over not having AI functions and Chromium still has serious limitations. But this is annoying. I have tried changing as many of the relevant settings in about:config that I could find to no avail. My PC an All-in-One 6 core Ryzen 7 with 16GB of RAM, which is far more than enough to handle the memory hog Firefox is (sometimes it eats nearly 2 gigs).
Any thoughts?
Thanks, Tom

I thought I had solved this by adding the website to the "safe" list - I really cannot say how frustrating this is if I am being locked out of even safe sites. - This is a browser issue (I'm not that naive).
There is no real response from Moacilla(Firefox) here apart from throwing the Rulebbok at me and saying "Read!". I can only do so much Tune ups" and shut downs and ensure drives are functional. Please advise on the Browser Cache situation, rspecially as BBC iPlayer is added to the "Safe List" and yet still throws up the 400 Bad Gateway error message - an early reply would be useful.

I love Firefox, I use it on all my devices. And daily I access facebook.com on this browser, it's been working flawlessly - until yesterday. Yesterday, using Firefox (ver 130.0.1) on my Windows 10 PC, I tried accessing a FB page which I visit sometimes: https://www.facebook.com/OpenOscillator
Rather than reaching that page, I got a white screen with this error message: "Sorry, something went wrong." And since then, even visiting the Facebook home page (or any other FB page) has the same error message.
Today I tried the same thing on my Mac (OS 14.3), using Firefox and logging into facebook.com, which worked as usual. But when I went to https://www.facebook.com/OpenOscillator, I got the same error message: "Sorry, something went wrong." And as happened on my PC, now on my Mac I can't access any FB page on Firefox.
And just to mention, I've rebooted both the PC and the Mac, yet this problem persists on both devices.
Trying this same exercise on Edge on my PC does not have this problem. Nor does it happen when doing this on Safari on my Mac.
So, this problem has only been happening on Firefox. I can no longer access facebook.com with Firefox. Do you guys have any ideas how to solve this?
Helpful to know: Do you have the same outcome if you visit this FB page: https://www.facebook.com/OpenOscillator
Thanks for your assistance! Steven

There's one specific field I fill in very often and for some reason Firefox is really keen on suggesting me two searches that I looked up more than a couple months ago, on a totally different site. I can't even remove these suggestions or add new ones. When I used Vivaldi, it'd learn what I insert (even if it'd end up suggesting tens and tens of options), while Firefox doesn't learn at all.
For sake of an example, let's say that the word I use every day in this field is XYZ. Not even once was it suggested to me, I've only ever gotten the two in the screenshot below instead. And I can't remove them using the Delete key as some other article suggested.
Speaking of which, I just noticed the same thing happen to the subject line in this form 🙃

Today I installed a clean WIN10 version on my PC, expecting to just log into firefox afterwards and have all the data back within minutes, but I forgot my Firefox password... As I'm currently in another country I also couldn't just log in on any of my other devices to recover the password, so I decided to reset it via the E-Mail... well aparantly changing your password deletes the sync data?? I'm guessing there is no way to recover the data? So I got a relative of mine to start my backup notebook which has not been synched for a few months but some data should've still been there, at least I had thought so... password database there was empty... and instead of synching the firefox landing page from my notebook where all my pinned pages were, it copied the page from the new device and wiped that as well... Any way to revert the sync changes on the notebook?

Good afternoon,
I have read in an article a statement that Primary Password encrypts all saved logins, therefore it is safer and recommended to use it. Well, I observed that it does not really matter if the password is set for the contents of logins.json, it does not change. What exactly is encrypted by Primary Password and how does it improve security?
I also tried to set the same password for different websites (I used a different mail tho) and the output in logins.json is different, which is even more confusing to me.
The output itself is kind of strange, the first part of it seems to be the same for almost all entries and looks like that: MEoEEPgAAAAAAAAAAAAAAAAAAAEwFAYIKoZIhvcNAwc.
