Firefox Support Forum

Hi, I had to erase all of my data in order to set up a fresh operating system on my computer. I made a firefox account and synced all my data before wiping my computer. I want to restore my previous sessions I was using before erasing all of my data, however can't figure out how. Thanks.

Hello,

Please can you tell me how I can click on a word document and for the document to automatically open without having to click the link in my downlaods? See screenshot of the download box that appears in the top right that I have to click to open the word document.

It does it for a PDF document but not for a word document.

Regards, Craig

The latest update has made it so Firefox opens the download panel every time I download something, a very obnoxious behavior when downloading a lot of files, and I can't find a way to stop that from happening.

[came across another question that brings up the same issue], but that one focuses more on a site presumably changing about:config rather than the issue of the download panel itself.

When i click on the firefox icon in linux apps on my chromebook, firefox does not start. When I try to re-install from terminal, it says it is already installed.

I uninstalled Libre Office and it apparently uninstalled the VCRUNTIME140_1.dll file s part of its uninstall process. From this point Firefox would open but would not connect to the Internet, either by clicking one of the links in the toolbar or typing the address directly. I have tried all the solutions I can find on the support pages, ranging from attempting to copy the file from another location to re-installing Visual C++ from the Microsoft website, both the 64 bit and the x86 versions. Having found and installed the latest version of Visual C++ I now get the error message "The procedure entry point _CxxFramehandler4 could not be located in the dynamic link library C\WINDOWS\SYSTEM32\MSVCP140.dll" at the edn of the installation process, and of course Firefox has not installed. Any suggestions for a way forward?

Every time I try to open Firefox it asks me for permission to install Firefox Software Updater. I then say no and Firefox opens with a notification to update to the latest version. I opted out from updates but the only option available is for the Firefox to ask before updating, there is no option to opt out definitively. Is there any solution to stop notifications and installing attempts?

Thanks in advance

Windows 10 - Lenovo Thinkpad X1 Carbon This fall after an update attempt, Firefox started trying to update every time it was started. Deleted Update files in Program Data. FF would restart normally one time. Update data files were always replaced and the update on every startup continued - over and over and over. Tried refreshing FF- same thing. Uninstalled FF this AM and tried to reinstall when I get the following error:

XULRunner Error: Platform version "94.0.2" is not compatible with minVersion >= 94.0.1 maxVersion <= 94.0.1

No FF - HELP!

I am trying to update but it just shows this all the time. I do not want to reset my browser because of all settings and stuff I would have to setup it all again I am afraid.

Firefox auto update has stopped working for me. Neither of the settings, see attached screenshot do anything, all I get is a popup saying a new version of firefox is available with a link to https://www.mozilla.org/en-GB/firefox/ I recently did a clean install of Win 10 pro x64 and this problem may have started then. I have another PC on the same network where auto download of updates are still working. Hopefully someone can point me to a way to get this working again.

Due to switching to a Linux distro with a slightly older version of Firefox, Firefox is complaining about the profile I copied in. The profile's compatibility.ini file says LastVersion=91.0.20210812023606/20210812023606. The current Firefox version is 90.0.2. Has the structure of the profile changed between these versions? If not, what's the best way to alter compatibility.ini?

Late last week, something changed in Firefox browser. I used to download csv files and Firefox would open them with the option to save as an excel file. Now it does not. I have to save it as csv then convert it to excel. It also doesn't seem to save my settings on the website I'm downloading from - I always have to manipulate the settings before downloading. It is a huge headache and I have resorted to using Chrome instead.

to upgrade my firefox browser from 32 bit to 64 bit, I was following the mozilla instructions to download the 64 bit version, but then uninstall the 32 bit version before installing the 64 bit version. However, using the microsoft store to obtain the 64 bit version, it didn't just download it, it installed the 64 bit version. Now I have both. Should I merely remove 32 bit, and my profile file will be accessed to complete the set up of the 64 bit version? Don't want to loose bookmarks, passwords, etc. by removing 32 bit version.

Hi Team,

I want to disable to "You have chosen to open this file" dialog for zip files but i am not able to disable it.

I have looked for some solution in google search that did not help.

Please help me on this.

My old computer crashed but I have access to the entire hard drive on my new laptop. I'd like to restore Firefox on the new laptop exactly as it was on the old laptop (bookmarks, tabs, etc.). All of the help articles talk about restoring from a backup, but I never made a backup since I obviously didn't know my computer was going to crash. Which files do I need to access from old hard drive and move to my new hard drive so that everything looks the same as before? Any help would be appreciated.

This question has been asked and answered many times before (e.g., https://support.mozilla.org/en-US/questions/1088420, https://support.mozilla.org/en-US/questions/1157159, https://support.mozilla.org/en-US/questions/1110373) but none of the solutions suggested are amenable to me. I need a way of installing Firefox on Windows that does not involve 7-Zip, which is blocked by my IT department, in any form. Is it possible?

I need to transfer saved logins from Firefox on a soon to be retired laptop to Firefox on a new laptop. New laptop has a few logins created while setting it up than I copied manually knowing that when I import from the old laptop with many logins, the few on the new laptop will be overwritten. My problem is that Firefox can export logins into a logins.csv file but it seems can only import from a Microsoft browser. Is copying the key4.db and logins.json from the old to the new the only correct way to do this? The old laptops logins.json file has a recent date but the key4.db has a 2018 date even though some new logins were saved last month. Do I only need to copy the logins.json file?

I'm buying a new computer and I'm wondering is there a method/procedure that I can use to transfer the entire FF browser including settings, extensions, bookmarks, and passwords without having to reinstall all those items individually? I know I can save and import bookmarks but what about everything else? I look forward to anyone comments. Thanks
