I am trying to download a spreadsheet file which has a .xlsx extension. Firefox insists on downloading the file (my default action) but I want to be given the option to open in my spreadsheet program (Libreoffice).

Looking in Settings and scrolling down to Files and Applications -> Applications, there are other spreadsheet formats present but not one for .xlsx. How do I add the "Always Ask" option for .xlsx files?

Libreoffice is the default system application for opening these files.

I use an addon to mute all tabs by default. The problem is that muted tabs have the MUTED text, which shrinks the size of the tab name/title. My old eyes can't deal with that very well.

Is there any way to prevent this text from showing up globally? Thanks.

I just upgraded to Monterey on my Mac running FF 101.0.1 (64-bit). I cannot add new search engines to my list of search engines. I'm trying to add DuckDuckGo without success. I have Google, Bing and Startpage. I click on Find More Search Engines, select and add DuckDuckGo but while it appears as an extension it does not appear in the list of search engines.

I would like Firefox to remember exceptions and store specific cookies that I need for the Microsoft authenticator, and other two-stage logins. Whatever setting I choose (untick delete cookiex and sitedata, assign websites to manage exceptions etc) upon closing Firefox everything is deleted, always. This means I can't use any authenticator to remember me when I want it to do so.

I used a third party cookie extension (Cookie AutoDelete) to whitelist some sites and it worked perfectly fine until an apparent recent update by Firefox. I am on Firefox 101.0.1 on Mac.

Any ideas?

About two days ago the cursor started disappearing / flashing when browsing in Firefox. It does not mater where the cursor is placed on the screen either the arrow or the hand will flash when moving. My system is a windows pro 10 system with all updates, last updates for W10 were made a couple of weeks ago, on Firefox whenever it asks to upgrade I do it.

Specifically: 1. If the mouse is stationary there is no cursor, if I move it the cursor flashes. 2. When the system comes up and I launch Firefox all is OK for about 2 – 3 minutes then the flashing begins. 3. If I stop Firefox ie “X” it and restart it the flashing occurs within 0 – 30 seconds. 4. If I restart the PC steps 2 & 3 repeat.

I have two other PC’s Windows Home, and Windows 7, as well as a laptop with Windows Home all with Firefox 101.0.1 all up to date all do not have the above issue. This does not occur with any other programs. I have two monitors, tried Firefox on each makes no difference same problem.

I have tried searching the internet and all I find is about Caret which is off. I uninstalled Firefox and installed it. That made no difference.

Any assistance will be appreciated.

Thank You

I want to select multiple Tabs from a bookmark folder to open in the background.

On Chrome this used to be quite easy: Just open the Dropdown, click whichever tabs you wanted to open with the Mousewheel and done.

On Firefox you need to enable new tabs to open in Background first. I managed to find the setting for that with google after a while. You need to go to advanced settings by typing about:config into your url bar.

Then you search for browser.tabs.loadBookmarksInBackground and click "enable".

But this didn't fix the other issue I had, that the dropdown menu always closes as soon as I click anything.

Is there a way so it stays open until I'm done selecting the pages I want?

Hi, just bought a new laptop which is loaded with windows 11, and I cannot download Surfshark vpn, I go to google and it will not even open any surfshark page, I assumed it must be something to do with safesearch, so I clicked on the safesearch button but it does not give me the option to turn it off it just states 'You don't have permission to change your SafeSearch setting. It's locked by the device or network that you are browsing on' !! how do I get over this? any help appreciated,

When I ask WordPress to "preview in new tab," I get a File Not Found screen. (See uploaded image.) This works fine in Chrome (which I rarely use) but not in Firefox, so I'm thinking it might be a Firefox issue. The Tablet and Mobile previews work fine, but they don't require a new tab. I thought it might have to do with pop-ups, so I made my blog's URL an exception. That didn't help. Then I disabled the pop-up blocker altogether. That didn't help either. I've never had this problem before although I've been using both Firefox and WordPress for many years. I'm working on an old laptop (current one is kaput), but I think everything's up to date. Windows 10. Any idea what the problem might be? TIA for any help. This is driving me nuts!

When I look up the error message I get, everyone I see who got it can't open Firefox, but I can open it fine. For me, I have Firefox as my default browser and when another program (tModLoader on Steam) tries to open it, it gives me "Profile Missing," "Your Firefox profile cannot be loaded. It may be missing or inaccessible." I don't know if it gives the same error for other programs because I can't think of any programs that open my default browser. When I switch my default browser to Edge, the program can open Edge fine.

Hi, I have this problem that is driving me crazy, I know it is not an issue with firefox but I really appreciate any help.

The problem is that there is a grey html code in inspector when rendering the html page, the grey code is not exist in my original file but that grey code I had already deleted it after using it a while, but it is still appears as grey code in inspector and this made me some issues in jquery.

So how can i get rid of it ?

Thanks

Unable to complete backup of firefox profile because of over-length file names in storage sub-directory. Is is ok to simply delete one or more file names which are old URL's and no longer required? Clear History All doesn't clean them out. (Firefox 101.0.1 (64-bit) on WIndows 10) thanks

Hello, I experience a XUL Runner error message after attempting to update Firefox and in following the guidance to rectify the error deleted the Firefox folder including the bookmarks. Is there anyway of recovering the bookmarks (maybe with a third party program) or are they lost forever? Thank you.

This question has to do with logging into web sites with an email and a password. Firefox 101.0.1 (64-bit). Windows 10.

On many sites, when I click in the email field, a drop down list of email addresses appears from which I can make a selection using the mouse or up/down arrow keys. Some web sites have as few as two email addresses in the drop down list, others have many more. I recall that one site has about fifteen email addresses in the drop down list.

How can I remove a non-applicable email address from the drop down list?

How can I clear the drop down list of all email addresses?

Thanks.

For some reason, whenever I load a pdf from within Firefox, I get a new tab with the regular toolbar displayed on top of pdf files, but the document itself is completely blank (see attached screenshot). This issue just started today and I assume it was a result of an update, since I don't recall making any changes to my settings (I'm using Firefox 101.0.1 on Ubuntu 20.04).

I've tried opening multiple files from a variety of sites with the same result. All of them open fine using my system's pdf viewer, as well as from within Chromium. I've tried disabling my plugins, putting Firefox into safe mode and resetting all the handlers, to no avail. Any help would be much appreciated.

Why are google sites (Youtube, Gmail and Search) getting disconnected when all other sites are still connected to the Net? This has been happening since November 2021.

When that happens I close the FF and then immediately open it. Now the google sites work properly.

Never had that problem with other sites.....never!

Why the hell is this happening? Is FF responsible or Google?

So what is the solution?
