In Firefox, after a reboot, how can I re open my previouse sessions?

Originally I had quite a lot of open browsers & tabs. Then I needed to do a reboot, and now I've lost those previouse sessions.

Usually I just open firefox, and this opens one browser, and then all of my previous browser, and tab reopen, but this time firefox crashed, and its popup said it needed to restart, but it would re-open my previous browser and tab, but it didnt.

After following the usuall firefox help giudes, it still wouldn't re open my previouse sessions. Now if I ask it to open my previouse sessions, it just opens the recent help giudes, and not anything before the crash.

So is there a backup file of myu missing sessions that I can roll back to?

Hello, I'm a web developer. I'm using the Firefox Developer Edition and currently working on a project that requires caret manipulation. I have this function right here that fetches the caret's client rect: ``` function getCaretRect(): DOMRect | null {

 const sel = window.getSelection()
 if (!sel || sel.rangeCount === 0) return null
 const range = sel.getRangeAt(0)
 const rects = range.getClientRects()
 if (rects.length === 0) return null
 return rects[0]

} ``` Here is where the issue arises. Suppose I have a contenteditable div with two line breaks (no new lines), and the second line is smaller than the first one. If the caret is positioned somewhere that is further than the end of the second line, and I press the down arrow key, then left, for some reason the caret rect I get has all values set to zero, like this: `{ x: 0, y: 0, width: 0, height: 0, top: 0, right: 0, bottom: 0, left: 0 }` I will add an image to explain further.

I don't have this issue on Chromium based browsers, but cross browser support is important for me.

There is one more issue to do with caret manipulation which is how contenteditable divs are handled. On a Chromium based browser, if I have a parent div that's contenteditable, then another div that's not contenteditable (contenteditable="false" explicitly), then two children divs which are both contenteditable (or more), I can navigate through the divs freely using the arrow keys and focus is managed better alongside event handlers. This is not present on Firefox, however.

If this is not the right place to ask for help then please guide me where is more suitable.

Lately YouTube playing videos have been playing super fast or skipping straight to the end. I mean, they are horribly fast.

Things to know:

  • I am posting here because I can't determine whether browsers may have settings unique to them that I need to change. This also happens in Chrome, but not Edge.
  • I was recently forced to upgrade to Windows 11 - I can't say this issue happened exactly at that time, but fairly recently after the upgrade. I am running Windows 11 Pro.
  • This does NOT happen when playing in a private browser window, either Firefox or Chrome.
  • Having the Mozilla VPN on or off has no effect.
  • I am sure the playback speed is set to normal. I have tried changing the playback speed to anything but normal and then back to normal and the current video runs correctly UNTIL I play the next video.
  • This does not happen with Vimeo.
  • It does not happen in FF for Android.

Any questions, thoughts, or advice would be appreciated.

For the last several weeks (can't give an exact date, but it's been more than just a couple weeks, less than a couple months), both my husband and I have had issues loading videos in FF. We both have the latest version of FF. I went thru "Fix common audio and video issues" and did all those things, as well as trying to load the videos in troubleshooting mode. Nothing has helped (tho now that i cleared all the cache, i'm gonna have to log back into all those websites :( ). Nothing else is problematic. Our internet connection is fine. In fact, my husband has resorted to using MS browser to watch videos--they load fine in that browser. I have no other idea what to do. Searching your database for "youtube videos load slow" only resulted in a couple hits with no resolution. Hopefully this isn't the third. thanks

Hi,

my firefox does not load any webpage no matter what Firefox profile I am using (created a new one for tests). I have a Win10 pc with Avast and Comodo installed, the system with the mentioned software and multiple different Firefox profiles was running since several years without problems.

A month ago I had the same issue with Firefox 126, which I guess was caused by a windows update, where I had trouble getting it installed. But after this (I had to increase the system reserved partition) Firefox was running without any problmes like before ...

Now no pages kan be load and always the crash monitor pops up.

Hi,

I'm switching from Edge and have a frustrating issue.

In Edge I am very used to having separate behaviour for links with left and middle click.

i.e. from Gmail, if I left click a link it opens in a new tab and switches to the tab, if I middle click a link it opens in a new tab but stays on the current tab

In Firefox both seem to be controlled by the single setting.

I have looked in about:config and tried changing a few flags but cannot seem to find a combination that works how I want it.

Can anyone help?

This is a real dealbreaker for me and I will switch back if there's no solution :(

When pasting text into Outlook Online the text removes the preceding space. A minor inconvenience but it does mean I have to double space before pasting.

Also after pasting text I get a paste box that locks out any controls unless I click out of it or press ESC. (image below)

Text being copied from inside Outlook doesn't pop up the box.

This problem is only happening with Firefox as using a different browser (i.e. chrome at office) does not do either of the problems. Anyway to fix either option?

I have a form with a date field. it should open the calendar downwards, and does so in a window with 5 tabs open. however in a window with 60 tabs it opens upwards - thus loosing it's head and the ability to change month and year. it's near the top of the form.

moving the tab from one window and back, without refresh etc, shows the calendar down wards (window with 5 tabs) or upwards (window with 60 tabs)

this is looking to me like a Firefox bug - I wondered if anyone has come across this interesting behaviour?

I apologise - ths was on my desk top - but i'm away so don't have many details. I can provide screen shots etc when I get back
