Diễn đàn hỗ trợ Firefox

apparently, programmers don't understand how aggravating not having backward compatibility is to the rest of us, so please bear with my extreme aggravation here. IF IT AIN'T BROKE, QUIT FIXING IT.

 firefox disabled my addons, thus forcing me to upgrade, and now I am angry. Tried downloading the new version several times. My os is as updated as it can get. Using the APT link from this site, it just shows garbage. Using the download for linux 64 bit link, it makes me jump through hoops and looks like it is working, but it looks different and none of my bookmarks transferred over. Closing it down and reopening it, I see the old version, thus making it look like I am possibly running both versions separately. Once the *all new singing and dancing special that is supposedly so much better than the old that some ignoramus decided I MUST use it instead of the old and functional one* is closed out, I see no way to reopen it. And neither version will enable or allow me to download singlefile. That is the only program I need from firefox at this time.
 Will somebody please show me, step by step, as if I am 5 years old, a back door that will enable my addons, before I go nuts and start beating programmers to death with reams of algorithms?

I'm having problems connecting to a server. I know it is a valid address because I can get it on other computers but it is now block on my computer. Is this a firewall problem and if so how do I fix it. the server address is" click.coverkit-mail2.com". How do I fix this?

Hello, Hi I recently updated (last night) and i didnt check all the boxes i clicked skip but NOW i can not recover any of the stuff from the night before is there a way u could help me ?!

Hello,

I wanted to customize my Firefox new tab with a local HTML file, such as "/path/to/my/index.html". It was possible to use this workaround: https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main

Which implied a configuration file (sometimes named "autoconfig.cfg", "firefox.cfg", "local-settings.cfg" depending on the guide since the name is arbitrary) with javascript code. In the new Firefox 136, this code fails to execute due to a new API being used.

If you want to customize your new tab, follow the previous guide, but on the configuration file write this code instead:

// My new tab
try {
  const ff = {};
  ChromeUtils.defineESModuleGetters(ff, {AboutNewTab: "resource:///modules/AboutNewTab.sys.mjs"});
  ff.AboutNewTab.newTabURL = 'file:///path/to/my/index.html';
} catch (e) {ChromeUtils.reportError(e);}

Note that the file must start with a comment

Adapting the "/path/to/my/index.html" to your needs.

Thanks to @mkaply (github) on this thread https://github.com/mozilla/policy-templates/discussions/1190 for the new API method.

I post this here in case someone has the same issue, because is quite recent and hard to find on the internet.

Suddenly Firefox will not connect to websites,Elders weather,message states security risk.You have been connecting me for years.Herald Sun you will not allow me to log in.All this suddenly started after last update.Not a problem with other browsers.

I'm viewing a pdf that seems to be made of stacked images. While viewing this pdf in firefox it has these black lines between images, as seen in attachment, these change slightly as I zoom in. These lines do not appear when viewing the pdf in brave, see other attachment.

Also, this happens both on my desktop and laptop that have very different firefox setups.

How can I fix this without fixing the pdf?

How could I even fix the pdf?

Dear Support Team,

Ever since updating Firefox to the most recent version my pause/play button does not work with tabs open. (like youtube, spotify(browser) etc.)

I tested for mechanical issues, but those do not seem to be the issue, as the key itself work perfectly fine. Different apps (like netflix, and spotify(desktop)) do not have this issue.

If you require any additional information in regards to this inquiry don't hesitate to ask.

Additional Information

Firefox 136.0.1 (20250310180126) Installed on: March 12, 2025 at 8:50:54 AM Status: The Update was successfully installed [copy and pasted from settings]

I don't understand why a page is not opening in normal windows, but it opens in private windows. I have tried to clear the cache, but I still have the same problem. Not all URLs have this issue; just some of them.

I require some add-ons for accessibility, which you abruptly disabled today due to "could not be verified". Also, all my other add-ons were disabled for the same reason - see attached. I read "https://support.mozilla.org/en-US/kb/add-ons-cause-issues-are-on-blocklist", which doesn't answer my questions. If you can't explain specifically why you did this, or tell me how to override your blocks, I'll uninstall Firefox from all my platforms!
