Firefox for Android Community Forum

I have this new issue, that Firefox needs like 3-4 seconds, before loading a page. It stays blank until then. Why has the Performance decreased so much?

Reinstall didnt help

Searched to why background tabs are not loading. Switched to tab Swiped down and still nothing. Using extensions decentral eyes and ultimate block.

Any troubleshoot tips? Ive cleared cache abd history, not fixing

Hello, I am Firefox Android user and i am having issue with Firefox while browsing substack.com website, When i open that website from a chromium based browser it works well but in Firefox it is slow and in my old mobile(android 9) which is even slower and i never wanted to open it. Twitter(X) is also heavier to open. I stopped using it from Firefox and using a chromium browser for these logins.

Firefox has all the features i wanted and i am satisfied that it is better than any other browser but lacks in performance. It is not smooth as Chromium browser.

Please look into it and it would be great if it just be more smooth like Chromium based browsers.

Thank you

Hello everyone,

While testing some fan-made game community websites, I noticed that Firefox handles them a bit differently compared to Chrome or Edge. For example, I checked https://nullsbrawl.tech/ (not an official site, just a community project) and saw that it loads more slowly and sometimes behaves differently in Firefox.

This made me curious:

Does Firefox have different handling for script-heavy or unofficial community websites?

What tools in Firefox Developer Tools would you recommend for debugging performance issues?

Are there guidelines for developers to make such sites more compatible with Firefox?

I’d love to understand more about how Firefox manages these situations.

Thanks in advance for your help!

Hello,

If the phone is not used for a while, it takes a very long time to open a page in Firefox. The bar immediately goes to about 25% and hangs. When it finally starts, it works. Sometimes it hangs during use, but usually the problem occurs after a long period of inactivity.

What I do know:

• The problem does not occur with any other browser or application.
• The problem occurs on different smartphones from different manufacturers running different versions of Android.
• Deleting and reinstalling Firefox cleanly (without any add-ons) does not help.
• Same problem over Wi-Fi as over cellular.
• Turning Firefox off and on again usually does not help.

I installed Waterfox and for a while there was no problem at all. Then it appeared. I noticed that at least in Waterfox, the problem does not occur in private mode.

This is an unresolved issue that has been discussed before. https://support.mozilla.org/questions/1416241
