This happens far too often, in the course of 9 months or more frequently. What is going on Firefox? v88.0.1 Windows 10

Constant script errors that freeze whatever program I am in, regardless of the option I choose - the popup no longer gives me a WAIT or STOP IT. The box comes up that says DON'T ask me about this again.

I do not want to copy passwords, more than anything, should I create a new profile. I do not want to deal with replacing or losing the file. When I attempted to load two other profiles over the last two days, both times FF crashed. I gave up.

I am NOW in Safe Mode and without errors, and it's hard to know which app is causing the problem.

Is there a new addon that will back up Firefox these days?

Suggestions? Seriously, FF seems to be a whole lot more trouble these days than she is worth.

Thank you.

How can I view a previous Bookmark file to restore one Bookmark on a computer running Windows 10?

I would like to selectively restore a Bookmark folder that disappeared recently. Since I have added more Bookmarks to my present Bookmarks file, I need to just copy or restore one Bookmark from an older Bookmark file. As I recall, this was easy using Windows Explorer but appears to be rather complicated in Firefox.

How can I do this without too much trouble?

Thanks

Tried to reset settings. Does not work. Went to about:config, than tab.mo / print.tab_modal.enabled set to false. Did this method before and it worked. Now this method does not work trying to get print preview back. Firefox is my web browser. I am in windows 8.1. Seems like Firefox did some updates again and now I can not get print preview back! WHY DOES NOT FIREFOX LEAVE WILL ENOUGH ALONE WHEN THEY HAVE SOMETHING GOOD? Bring back the old classic print preview button back and leave it. Now how can I get the old print preview button back???? Need help!! Thanks philm

Hello, today I was surprised with a update ver.88 -> 89. It completely changed the look. Few weeks back it was similar with Thunderbird.

I hate this look. I want old look back - how to do this. I tried rollback to 88, but it ask to create new profile - after copying all content of profile it dose not work...

Is there a way to change look of 89 to look exactly like 88 ?

why why why .. again ..

Update 89.0 changed the browser theme to something I don't like, too pale and pastel. Options to change back to what I had aren't available. The options presented are now uglier than this sick looking theme.

How do I undo 89.0 update? Pretty much looks like (from release notes on another post) 89.0 has nothing at all to do with security and it's just someone at Firefox wanting to change things just for the sake of changing things.

I hope Firefox isn't going to start doing silly things like moving the first floor to the second floor and the second floor to the first floor just because some administrator feels like it.

I'm trying to perform the clean reinstall for Firefox on my computer. But, I see the instructions for the uninstall, Delete the Firefox installation folder, which is located in one of these locations, by default:

   Windows: (Note: Check both folders.)
       C:\Program Files\Mozilla Firefox
       C:\Program Files (x86)\Mozilla Firefox 

Being I'm not computer wizard I had trouble finding the location of such folder. But when I accessed my program list in my windows program list I see a program named Mozilla maintenance service. When I click on that I see a format/window to "uninstall C:\Program Files (x86)\Mozilla Maintenance Service\." Is this the program/folder I need to uninstall to complete the proper instructions I need to perform a clean install? If so, when I delete it I then reinstall Firefox once again after the uninstall procedure? Is performing the uninstall procedure going to screw up my Firefox browser and my many bookmarks I have accumulated over the years? Can someone please help and explain? Thank you.

FFox 92 update today. Menu spacing went to double. No shock there. Found the CSS code below for UserChrome.css and set it up.

EX.

menupopup > menuitem, menupopup > menu {
  padding-block: 4px !important;
}
:root {
  --arrowpanel-menuitem-padding: 4px 8px !important;
}

EX:

menupopup > menuitem, menupopup > menu {
  padding-block: 0px !important;
}
:root {
  --arrowpanel-menuitem-padding: 0px 0px !important;
}

But, it doesn't get any smaller than the above 4/8px set up. Bug? Perhaps there's another CSS setting to be tweaked for V 92? I do not have any other CSS for these items elsewhere in my UserChrome file.

Today I updated my Firefox Developer Edition to version 89.0b2 and now I just can not look at this browser anymore, "Inspired new tab design" is taking too much space and now became largest and at the same time least information-dense panel in my entire desktop! I searched around the web for a bit in hopes that I will find a theme or an add-on that will revert this particular change but no luck. I really want to revert to old UI look (at least tabs bar), there should be default theme or option to get back to old style. After some investigation I found userChrome.css but don't really want to install it (maybe this is actually the way of doing this kind of styling). Please help me revert UI design to old one.

Hello dear Nerds

With the last update the Bookmarks have a wide distance when listed. Too wide! I have to scroll down endlessly to find things. Before they were neatly narrow and you could see twice as much. Kindly repair this next time please. Or can I do this? Best Ursula Zürich

Several weeks ago, because it seemed to be a Gmail-tab-only problem, Firefox Support advised us to contact Gmail Support.

It is now clear that the problem is with the Firefox browser. The attached screenshot shows an example of an affected tab.

Please fix this. Multiple versions of the same tab waste RAM and other memory, especially on a limited-memory device such as a laptop.

Ever since IE changed to tabs on top firefox coders followed like mindless automatons without any regard to/for Mozilla community and users. We are sick and tired of being ignored. We want/need tabs bellow address bar. Now, tell us how to simply get tabs below address bar or tell the coders to provide us with the option. And, we don’t care about any excuses as previously provided or outright ignored by them.

Hello all,

Although I have just updated Firefox to the last version hoping that the problem might be solved, after using the browser for a while and I google searching something, I get a blank page that does not load. Accessing other websites (bookmarked pages) might work sometimes though, but accessing the home page (google, google translate) just displays a blank page, no error message. I have started Mozilla in safe mode (troubleshooting mode) and the problem persists.

I have already deleted cookies, created a new profile, and reinstalled Mozilla and nothing seemed to work. The behavior is rather unpredictable and odd as I could not identify a pattern for the instances it happens. Exiting the browser and restarting it seems to solve the problem for the moment and then the behavior reoccurs. Also, sometimes after getting blank pages, taking a break or just using other browsers the problem is solved by itself temporarily. This does not happen when accessing Microsoft Edge.

The ability to edit and customize the headers and footers for printing was one of my main reasons for switching from Chrome to Firefox. Now I can't find where to do this. I don't know if it was a recent update or what but I am using Windows 10 Home. Please help so I don't have to find a new browser.

For the past two weeks, I've noticed that embedded maps make my browser immediately crash. I initially thought it was a Firefox problem, but I have been having a similar issue with Safari. This does NOT happen on my iPhone using the same two browsers. This also does not seem to effect Google Maps or embedded Google Maps, but embedded maps from other services. Anyway, I'm posting here because Firefox conveniently provides crash data, I'm not sure what else the cause could be and I'm hoping someone can help.

Two websites this has been consistently happening with are The Empire State Trail bike path (https://empiretrail.ny.gov/) and a NYC vaccine finder website (https://vaccinefinder.nyc.gov/). Firefox immediately crashes, though with the EST website it seems to be tied to the pathway of the trail being drawn (crashing after I've zoomed in a few times and the path has to regenerate). Safari doesn't totally crash, but forces a site reload and after it fails a second time says it can't display the site.

Any ideas what the issue could be? I'm on the latest version of Catalina (10.15.7), Firefox and Safari and seem to have all security updates for all.

Here's a link to the latest crash data: https://crash-stats.mozilla.org/report/index/1389c870-51cf-4790-b0a0-fd01f0211202

Ok, this might be REAAAAALLY weird that i'm talking about a firefox version that was released in 2012. But i really need it on this windows 2000 VM. The problem is firefox 9 - 12 is not loading any websites or webpages. It crashes instantly upon opening them. Versions lower then firefox 9 - 12 work flawlessly. Probably nobody will answer this but it is really important for my VM.

Posting on behalf of a user who hit the VPN inbound queue with a question better suited for this forum:

The tab bar, toolbar, and address bar placement in my Firefox Desktop browser has recently changed. I have been trying to revert these recent changes as they interrupt my current workflows.

I DO know which prior profile save contains the desired info however, it contains many files and I DO NOT KNOW which files I need for the bars to be restored. If you could provide me the name(s) of the file(s) that holds the bars data, I am probably saved, hopefully saved.

I would like to set the tabs to display below the address bar in Firefox 89 64bit. I believe the setting is in about:config but I can't find it. Firefox does this every so often and I wish they would just have a button to say tabs on top, or tabs below address bar.

Recently I upgraded my Windows 10 to Windows 11 and since doing so, I've had consistent errors while browsing the web on Firefox. Most notably the "Humm. We're having trouble finding that site." error message.

For example, when visiting, say Verizon.com, the tab will display the aforementioned error to which I press Try Again and the website loads correctly every-time. No hiccups on the refresh.

I've tried the following:

1. I've performed a completely clean uninstall of Firefox and then reinstall
2. Cleared all browser history/cache
3. Removed all extensions
4. Disabled IPv6, HTTPS Over DNS, No Proxy
5. Ran through Firefox's troubleshooting
6. Used Firefox Troubleshooting Mode in the Browser
7. Tested that the problem does not happen while using Edge

I've never had a single problem on Windows 10 with Firefox. Curious if others are experiencing the same issues and if there are any fixes. Nothing else on the PC has changed.
