Firefox Support Forum

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?

FF doesn't reliably open my last session. It used to but for nearly 18 months now it has become hit and miss. I have FF docked on my taskbar (Win 7 sp1) when I click it some times it opens all my tabs (I have it set to do that) but more frequently it doesn't and just opens one tab. Usually I catch it and in history select the tab showing many other tabs and I get it all back, but this doesn't always work like today, no option to do that because there's nothing there. When is it likely to be fixed, I've been complaining about this for months. I've even suggested FF collects a stack of last sessions (say 20) each time a session is closed and have a fixed entry for that in the menu, but nothing seems to change. I'm heartily sick of it, it's such a basic requirement of any browser and yet with FF it's just a pain in the neck.

Dear Sir,

Now there is some sort of an error message of HTML5 video

I have one site that produces PDF files that Firefox will not open correctly, my other browsers do not have a problem with PDF. What should I be looking for to correct.

I have been using igHome as my Firefox home page for many years. Yesterday when I opened Firefox multiple porn pages kept opening. I uninstalled and reinstalled Firefox and that didn't help. I tried CCleaner and Malwarebytes to scrub any issues but that has not helped. HOWEVER, if I log out of igHome the multiple pages do NOT open, so apparently this problem is related to my igHome login.

I am using Windows 7 on this laptop and I understand that is no longer supported, but is there any way to remove whatever is causing these sites to open when I log in to igHome?

Please note this problem does not occur on a newer laptop running Windows 10. I am able to use igHome with no issues.

Thanks!

Since support is being discontinued for W7 Firefox, would someone please recommend the best version of Firefox for Windows 7? Security is not a concern, since I have reliable 3rd-Party security setup(s) for my Windows 7 systems.

Thanks!

I want to use a command option to open a new blank tab in a specified portable instance of Firefox using a specified profile.

I constructed my command like this:

"Path-to-Firefox-executable" -profile "Path-to-Profile" -new-tab "about:blank"

It partially works (it opens the correct instance of Firefox and uses the correct specified profile) however it always opens about:newtab instead of about:blank.

Seeing as I am specifying the exact page to open, any New Tab settings in the browser should not matter, and I should just get the page that has been specified in the command.

If I manually type about:blank into the url bar, then a blank page opens as expected, so the url is correct, it just won't work for me as part of the above command line.

Does anybody else have this issue? How can I get this to work correctly?

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

I have used FireFox for years Now I can not download VPN as it requiers W 10+ I can not afford new computer, I am a Disabled Viet Nam Vet/ A MARINE I dd not what all these new apps and maybe Windows is blocking download - HELP

I start Firefox from a batch file (Win7) on the first boot of the day. Manually I choose my "NEWS" bookmarks folder, then slide down to "Open all in tabs". (attached image) (Then I go pour a coffee while the news article tabs open and load data!)

Please and thank you, is there a way to specify this action from the command line? And if so, what is it?

I believe that I could use such a mechanism in other ways, such as opening all tabs in my "Forums" folder of bookmarks, or on Mondays, opening all tabs in my "Weekly" bookmarks folder.

Thank You, Chris

I tryed Firefox 115.8.0esr and 115.9.0esr 32Bit on Windows 7. (78.15.0 works) Firefox crashes(the whole program, i mean no tab) on "about:support" or some pages on support.mozilla.org like https://support.mozilla.org/de/kb/firefox-leistungseinstellungen always reproduceable.

I disabled all Addons, i disabled this power optimizion setting, removed usercrome.css same. With Firefox savemode it dont crash. Spyware is blocked, means datareporting/telemetry/ping by disabling the options and empty the urls (like on FF 78 but it dont crash). Somewhere i read firefox can crash on a empty url, but i assume its fixed long time ago. A wrong, unreachable or empty url should not crash on well programming. Think about countrys that blocks urls, adblocker, pihole and so on. I dont remember about what url i read.

Does the savemode revert all about:config settings? What does support.mozilla ask the browser that causes the crash? It know it seems to identify the Browser, but usual its done by useragent and no "internal" communication.

Then FF always crash on ebay.de search if you scroll or change settings while the page is not ready. Spyware is too blocked by Hardware, ebay may wait for some ad? But thats already on FF78 but on 115 it seems more often, this was not with FF 52. But some sites including ebay stops to work with FF52/78 so no choice.

I noticed that after the recent updates, the pop-up notification for blocked pop-ups has changed from yellow to white.. This makes it very difficult to see and I almost missed it. Is there a way to revert this change using userChrome.css?

I don't understand why this unnecessary change was made. I already have my own userChrome style for the entire Firefox because it was frustrating to constantly change it back after each update.

I would appreciate any information on how to revert this change.

Thanks.

Hello, I am using firefox 83.0 and I don't want to update it (Why? Because I've an old PC with poor hardware and the playback of online videos is lagging/shuttering in releases after 83.0)

BUT firefox 83.0 doesn't support private fields which make some webpages unable to be loaded. the private fields was supported starting in release 90.0 and I'm using 83.0

So, I need a way to make firefox 83.0 support private fields, Is that possible? Is there a certain files should I edited or replaced to make it support private fields?

Any ideas would be appreciated.

Dear ladies, dear gentlemen,

on another Computer, when using Firefox, I am now constantly getting a Norton notification of a malicious domain request 22. The problem does NOT arise with the Opera browser installed on the same machine. What shall I do? Uninstall Firefox seems to be the best solution. Scans do not reveal presence of malware. On this computer, similar OP, this does not happen, but I use it much less.

Thanks a lot, Alexander
