My system disk failed, so I had to restore it from pretty old backup, with old Firefox version installed and old profile data. Now I want to start Firefox and reopen all my recent tabs from Firefox Sync, but not from my local (old) profile. How should I proceed?

Per an article on yahoo news, I decided to clear data by going to: Settings->Privacy & Security->Cookies&Site Date->clear data

In hindsight, this turned out to be a mistake. Previously when using yahoo mail, it let me stay logged in for two weeks. Now I have to log in each time. There are also 2 or 3 other sites that logged me in automatically, but now have to log in every time.

How can I undo what I did?

Thank you for any help you can offer,

Carter

'On my firefox browser, the bookmark toolbar disappeared and wans moved from the left margin. How do I get it back to the left margin and auto open on every tab?'

I'm not sure what happened in the latest update, but it broke the Canvas website that I use regularly for classes and homework. I've checked and confirmed that Canvas still works normally on Microsoft edge.

Extensions shouldn't affect the website because Canvas was working normally until the recent Firefox update.

Anyone know how to solve this problem?

I am getting Access Denied on many web sites that i have used frequently. For example, for the site https://www.apartments.com/ I get this message:

Access Denied You don't have permission to access "http://www.apartments.com/" on this server.

Help!

Hi I'm using Firefox to open PDF files from a network directory. The reason is that it's probably the best PDF manager I can find.

• What I wanted to do was have an option to open the file in a native viewer such as Adobe, this way look at 2 parts of the document at the same time.

At the same time keep it in Firefox.

Is there a setting to do this or an add-on. The add-ons I've seen are meant to open directly to Adobe from a web link I think.

I know this has been asked before but I've looked through past instances and couldn't find a solution that still seems to work as of 2022. I need a way to disable certain built-in Firefox keyboard shortcuts. I recently switched from Chrome to Firefox but if I can't disable the ctrl+i and ctrl+b keyboard shortcuts I'm going to have to switch back. I use both very frequently for work, so their non-functionality in this browser is genuinely impacting my productivity and it's getting really frustrating.

Hello. On some of my sites that i try to get onto with Firefox its says performing TLS handshake then it goes to Secure Connection Failed and says PR_End_Of_File_Error. I am totally updated with Firefox, plus i cleared out everything in my history. That did not help. When i tried to get onto these websites with Chrome web browser i do not have this problem at all. Why is this? I have BitDefender Total Security newest version for home. My firewall is through them along with virus protections. So can you help me out with this ongoing problem getting on some websites?

A lot of times while coding I press Ctrl+S to save Visual Studio Code and update live server (while watching on firefox the result). The problem is that when I'm focused on Firefox Ctrl+S pops up the Save Page window and (if I held Ctrl+S for more than a split second) it crashes (probably due to multiple popups becoming unresponsive). The mouse can't click to cancel the pop ups for saving the page nor interact it. I have to kill the firefox process and restart it. I've been looking into disabling Ctrl+S shortcut in Firefox with no success (extensions are deprecated or require too many permissions I'm not comfortable with).

Would someone help me to disable Ctrl+S or enlighten me on how to not have firefox crash every time I accidentally press Ctrl+S?

Thanks!

Firefox eventually crashes every time I use it, usually when there is about 165 mbs of data. I can relaunch it by both using CCleaner to clear the browser in addition to going to Firefox preferences and deleting data and history. I don't have Flash or Silverlight. I have refreshed Firefox a number of times and completely uninstalled it using the MacCleaner Pro App Cleaner and Uninstaller and reinstalling it using Mozilla's online download link.

Recently some programs, such as Word, are opening behind the browser window, so the only way I can access them is by shrinking and moving the browser. I also find that when a program does open in front of the browser, (as did Excel just now, I am unable to pull the browser window back to the fore without shrinking or closing the app window - ie closing excel - as I did just now. I have tested this in Chrome and Edge, and they seem to behave just fine, so the problem would appear to be with Firefox settings, but I can't locate a setting to tackle this.

Hi I am using firefox in arch linux 5.17.9-zen1-1-zen kernel and after the new firefox update I can't right click in firefox. Whenever I right click the context menu shows up for 1 sec and then it automatically takes me to the previous page. Click on the image automatically prompts me to download it although I don't want to download the image. Is there anything I can do to fix the issue ?

Clicking on the spacebar, does not produce a space between words, when typing text. I'm using a Mac Mini M1, on macOS Monterey (V 12.4), along with a Logitech MX Keys for Mac keyboard.

This happens randomly, for instance, on this very message. I previously posted a question regarding another problem that I came across with the same hardware and Firefox.

I found the solution to that problem by disabling an Extension in Firefox, however, I can't begin to think where to look for what setting, that may be causing my current problem.

I moved my old hard drive to a new ssd. Everything works but Firefox . I uninstalled and reinstalled when i try to use it I put in a search term hit enter and nothing happens. Also the drop down on right side nothing can be used

When I did the reinstall a error message came up about The code execution can not be found because VCRUNTIME 140-1 was not found reinstall Firefox again I did that did help

Thank you in advance

In my Bookmarks Toolbar I have created a Folder, 'News' and placed it at extreme left, next to the 'Show Your Bookmarks'. By clicking on the 'News' Folder I can see and select any of my favorite Web news sites. Very handy. Today, however, when I clicked on the News folder my 73-year-old hand accidentally dragged the News folder on top of the 'Show Your Bookmarks' icon and the News folder disappeared !! I can't figure out where it went !! Help !!

When I open gmail in Firefox browser, I lose the connection very often, it also happens with google drive. But it does not happen to me if I use Outlook from the web, I only lose the connection with Google from Firefox.

However, if I open the same thing using Google Chrome, this does not happen, it works correctly throughout the day, and I do not lose the connection.

My version of Firefox is 100.0.2 (64-bit) on my notebook I have Windows 10 Pro installed.
