I use Mozilla as my browser on Windows 7. When I click on Mozilla I get an Error page which reads, " Server Error in "/" Application. Runtime Error. Not sure how to fix this. Can you help. Thank-you

I just got a new computer, and I'm trying to copy-and-paste a profile over from the old computer to the new one, but this doesn't seem to be working. Firstly, when I click on the Firefox icon on my new computer (Windows 11), the profile manager doesn't start up, so I can't choose the old profile. I've tried copying over all of the old files into the new profile folder, and that didn't work, either. What's going on?

When a new bookmark is created it goes to the end of the bookmark listing in the left panel. How can I force Firefox to automatically put each newly created bookmark in the correct alphabetic position in the left panel Bookmarks panel? I DO NOT want to alphabetize the entire panel, I just want each newly created bookmark to go where is alphabetically belongs. I do not use folders so have one long list for bookmarks menu. thank Bob

Firefox detected a potential security threat and did not continue to noodlemagazine.com because this website requires a secure connection

On homesnap web site I get a pop-up window for homes.com. I can't get back to homesnap & I can't get rid of the window to redirect to homes.com. What can I do? Thanks

I've used Firefox for years and I like it!! I'm just wondering if there is anything Mozilla can do to counter the apparent collusion between YT and MS to coerce people into using Chrome, by means of YT degrading their videos when playing on Firefox?!

To log into my mortgage lender's site I have to enter my email address. Beside this field is the Facebook container symbol; mousing over it warns me that if I enter my email here, Facebook can track me. Mortgage Lender used to allow me to log in with a user name, but now requires my email address, which apparently gives Facebook access to track me. Tried speaking to the lender about this, but they simply assert there are no Facebook trackers on their site. So, any workaround for this besides just doing all my business with them by phone from now on?

At some point in the winter of '21 I created a folder of bookmarks that was saved in the 'bookmarks menu'. At a later date, hard to say when but probably '22 or early '23 I deleted these bookmarks. I now desperately need to recover them.

The oldest auto-backup from 'Manage Bookmarks' -> 'Import and Backup' -> Restore is dated mid '23 and does not contain the deleted bookmarks.

Is there any hope of recovering them? For example via the Recycle Bin or by using a data recovery tool? Or will they have been overwritten?

When I clicked troubleshooting mode FF unexpectedly closed my Private browsing session and all the tabs. How do I reopen them?

I did not expect FF to close on me like that. I thought that as I was in a private browsing session FF would have warned me that it was about to close had it been necessary.

I'm guessing that my open tabs have been lost permanently because you didn't warn me and that all that time I spent is now wasted.

Life is really simple except that other people make it problematic.

Just a couple of quick questions for CSS coding as of Firefox 115:

What CSS code refers to the shield, padlock, permissions, or all other toolbar buttons in the address bar?

When using control to select multiple tabs, what code refers to the outline and text color of the tabs?

Images attached for reference.

Thanks in advance!

I'm still using windows professional 7, it works for the most part. Unfortunately often the browser won't load or it will load and runs very slowly, then it shows a box saying close previous firefox. When it is running slowly I often have to hit the browser many times until the box shows up saying close previous firefox. Is this something to do with windows 7 or another completely different issue.

FireFox has been crashing for the past few weeks, that is not the biggest problem, but it also does that during a restore session. Which makes me lose everything I've been doing, the simplest solution I've found is reopening almost all of the tabs from last week, which is about 600 tabs that I then go through and get rid of what I don't need. That takes a lot of time, and my internet connection is not that good. which means that I will lose a large part of what I was working on the next time FireFox crashes during a restore session. Is there anything I can do to prevent Firefox from crashing?

Subject says it. Chrome has taken over as my default browser. Need to keep Chrome on my Win7 PC, but want Firefox 115.2.0 to continue as my default browser. Please advise how to get back to Firefox as my default...

Hi there,

In the search settings, I have set DuckDuckGo as my default search engine and removed all other engines from the list of options. However, I often notice that Google (which I have removed from the options) has replaced DuckDuckGo as my default search engine and has again been added as an optional search engine, without me knowing. Why is this happening? Is it possible to stop it happening, and if so, how can I stop it happening?

Cheers Paul

I have a PC with Windows 7 64b that I have updated after having synchronized with two laptops and one Android. After that Firefox works on all the units except the PC. On that I can see all Firefox shortcuts and Firefox account. But when I try to connect to a web place the screen is blank. I have also tried to sut down the computer and start again. No change. RAM memory is okay, storage on unit C: is a bit small and the CPU is Intel Core i5 3470@ 3,2GH instead of Pentium 4 and 4GH. Should I go back to an older version of Firefox that is not som demanding or is there someting else I can fix?

Do you have my e-mail address? bernt@bernt-lindberg.se
