Diễn đàn hỗ trợ Firefox

I use firefox on Mac OS 10.14.6. Every time I quit firefox (Stopping the program, not simply closing all windows) everything is reset to defaults. For all intents and purposes, it's as though I deleted and re-installed firefox every time I quit out of it. Bookmarks are removed, and any default bookmarks I removed are re-instated. It also opens up the set-up and privacy web pages that it does for the first time when you open it. None of the preference files are locked, it's set to remember history and I'm not permanently in private browsing, it's not even supposed to delete cookies. It's been like this since the moment I installed it; refreshing firefox changes nothing, uninstalling and reinstalling it also changes nothing. The only thing that stays the same is that my computer keeps firefox as my default browser.

I recently have a new laptop (Dell Inspiron 15 3593) & installed Firefox. Every time I watch a video on Youtube and click on the logo to return home, I get logged out and when i try to login I get this “'405. That’s an error.” message. I tried doing the same thing with the other browsers (Google Chrome & Microsoft Edge) & they work perfectly. I also tried reinstalling Firefox but still the issue is the same & Firefox on my old laptop doesn’t have this issue. Can anyone help me with this one?

Hi,

From two to three weeks ago, every time I open windows, my firefox browser reboots twice. It does not give any error message and when it reboots it goes back to home page. I removed all extensions, then I updated the browser and the Graphic Card, in vain!

Any help please

Why was one of the add-ons able to take over control of the entire browser and add-ons in it and establish its own rules? At the same time, it deleted all history and open tabs and my profile (firefox) did not save anything and did not restore the current session after reinstalling the browser, although it is worth remembering the current session and tabs there. I tried to remove this add-on for a long time, but it blocked all possibilities to do it. The browser began to open with one tab with an incomprehensible address, which was not even displayed correctly, and any attempt to search for something led to the opening of an incomprehensible search engine, but it was possible to go to Google. I don’t remember the name of the search engine, alas, it was several months ago, there was still no time to write to you. Oh yes, on the screenshots everything is in Russian, I'm not sure that you can fully understand them, and if so, write to me about it and I will try to translate the key positions. I would be glad to hear at least some thoughts on this in my profile mail. Here are some screenshots:

Possible coincidence, but suspicious! Re: Firefox 81 [from the 100s of ‘hits’ I see here now, likely a Ffx bug]

Written from wife’s PC since mine is now crippled. I upgraded to Firefox 81 on my own PC, reluctantly, for “security” fixes, NOT for the big new feature I don’t want. Last night I downloaded v. 81 then closed Ffx and shut down the PC late at night. (It runs Win 7 with all the relevant updates I know.)

Today after booting, it showed my normal desktop. But my email app (located on D: drive) would not open either from shortcut or from Programs menu. Same for all the other apps I tried to open, even on C: drive, including ms_Office. Almost any app would bring up “server execution failed.”

Now, after a few hours on “Sleep” then reopening: --Nothing but a black screen (w/cursor) for 5-10 minutes anyway; --Later a plain blue screen, in small type on lower right: “Windows 7 build [no.] / “This copy … not genuine” –although it came installed, straight from Dell!

I hope mozilla can help cure this in its paralyzed state – and get me back to v. 80.0.1 that worked!

Hi,

I'm used to deploying/configuring Firefox in an organization with settings in autoconfig.js, etc. Recently, I've seen that some settings are honored, others aren't, so I started using policies.json as well as keeping my autoconfig.js. Can they work together?

In any case, I am unable to disable app update with either of them. I have the following in policies.json:

{

   "policies": {

"DisableFirefoxAccounts": true, "DisablePocket": true,

       "DisableAppUpdate": true,

"DontCheckDefaultBrowser": true, "DNSOverHTTPS": { "Enabled": false }, "Certificates": { "ImportEnterpriseRoots": true } "PopupBlocking": { "Allow": ["http://10.215.144.56:8080", "https://intranet.mydomain.org"], "Default": true | false, "Locked": true | false }

   }

}

I'm also showing a snippet of my autoconfig.js file:

lockPref("app.update.auto", false); lockPref("app.update.enabled", false); lockPref("app.update.mode", 0); lockPref("app.update.service.enabled", false); lockPref("app.update.disable_button.showUpdateHistory", false); lockPref("app.update.url", ""); lockPref("app.update.url.details", ""); lockPref("app.update.url.manual", ""); lockPref("signon.rememberSignons", false); lockPref("extensions.update.enabled", false);

The problem is that when I start Firefox 78.3.0 ESR and go to the about Firefox window, I can see that the app update is not disabled.

How can I make sure that all the above settings in autoconfig.js are actually honored?

Thanks

I hit bookmark this page and the window opens, 1st screen capture.

When I click on "choose" see what happens in the 3rd screen capture.

I can choose the sub folder to save the bookmark to. BUT I now CAN'T scroll down the screen to hit the save button. Because the bookmark window doesn't have a scroll bar or a way to make the bookmark window smaller. This is frustrating. Firefox is having other issues not connected with this issue. But the overall picture is getting me to the point of dumping Firefox and going to Google Chrome.

When opening firefox it opens to newtab instead of my homepage which is Yahoo. If I click on the home button it will go to my homepage but I shouldn't have to do that every time. I have cleared the cache and it will work once or twice only then back to the newtab page.

Starting this morning I'm getting a weird error message when I try to share articles from things like Daily KOS from my email. This is the message: "App Not Setup: This app is still in development mode, and you don't have access to it. Switch to a registered test user or ask an app admin for permissions."

  I have no idea what that means and I don't see any references to it in the community answers. Suggestions?

Thanks.

Hello All, We are using Firefox from 10 years and It was good experience all the time. After updated every time crashing when i visit my company site Bis Kerala Matrimony . We have checked our website code and we did,t find any error other browser all working fine and using windows 7. How to fix this problem?

Hi,

I've been visiting several sites with maps enclosed. An example: link text

The same in my wordpress site. Whats going on, an more important, how to tackle this problem? So Firefox doesn't make friends. In particular if Firefox doesn't give a solution.

today I noticed that my webpages, only with Firefox, not with other browser, shift toward left on clicking (any hyperlink) . You can see on this my website my website .

Hello everyone, Trying to find out if my Mac Mini has been infected with flashback. Using this terminal command,

defaults read /Applications/Firefox.app/Contents/Info LSEnvironment,

I got this response:

{MallocNanoZone = 0;}

It should read:

The domain/default pair of (/Applications/Firefox.app/Contents/Info, LSEnvironment) does not exist

I cannot find anything about this and was wondering if it indicates anything malicious. Anyone know about this? Thanks.

About a week ago FF starting to close by it self or freeze.Instaling new one didnt help,switching on-off all addons didnt help,only normal works in safe mode i think.I created fresh new profile with fresh new downloaded FF and gues what?it is still self-closing,no crash reports-just self closing or freeze.

I just want to report a malware attack I experienced yesterday (8/29/20) which seemed to affect only Firefox.

After I clicked on the link to Boston Globe article my Firefox screen was filled with what purported to be a message from Microsoft saying that my computer was blocked because of suspicious activity detected on my IP address and telling me to call 1-888-222-6480. It also wanted me to enter my Microsoft password and warned me not to turn off my computer. The whole thing looked suspicious to me, especially since a pop-up window on the page requesting me to enter something (I forget what) showed a URL that began https://drink3.ga At some point, I don’t remember whether it was when I did turn off my computer or whether it was because I didn’t respond to messages commands, the malware did something to make my computer heat up and caused the fan to run at a ferocious rate until a message appeared that a break point had been reached and Firefox closed down. I was then able to use another browser to get to the Firefox support page and learn about refreshing Firefox. After I did that, Firefox behaved normally.

I am sending this to you because it’s something you should be aware of and represents a vulnerability in Firefox that should be addressed.

Every version from 69 to 80 crashes and then will not restart unless I log off or restart the computer. The crashes happen every time. I have uninstalled. I have have installed different versions. It will not start in safe mode after a crash. I can start in safe mode after a restart of the computer, it still crashes soon after.

I only have windows defender at the moment and I have that turned off right now. Windows 10 Pro.

Any help would be appreciated.
