Firefox ho an'i Android Community Forum

I sometimes notice that pages take longer to load in Firefox, even when my internet connection seems to be working normally. The issue does not happen on every website, so I’m trying to understand how to identify whether the cause is Firefox itself, an extension, cached data, DNS, or the website/server.

What Firefox settings or troubleshooting steps should I check first to determine what is causing the slow loading?

I have already tried refreshing the pages and checking the connection, but I would like to follow a more systematic troubleshooting process.

Hi everyone,

I've noticed that Firefox for Android has become noticeably slower when loading certain websites, while the same pages open quickly in other mobile browsers.

I've already tried:

Clearing the cache Restarting the app Updating Firefox to the latest version

The issue still occurs on both Wi-Fi and mobile data.

Has anyone experienced the same problem? Are there any settings or troubleshooting steps I should try to improve browsing performance on Firefox for Android?

Thanks in advance for any suggestions!

the app just asked me if i my experience was good and this is where the link brought me. The firefox mobile app on android is performing teribly over last few updates. websites take 1000x times longer to load some elements. it feels like the cache gets full after loading 10 images. youtube videos take nearly 30 seconds to load on gigabit internet. marketplaces just wont load images. it gets stuck buffereing images and videos. the easiest fix is to switch browsers which completely eliminates issues. this is happening on multiple android devices. either the code for this app is ruined or compromized. the problem is not on my linux or mac devices. I really have loved firefox up to this point, and its sad that after 1 month of questionable management the browser is starting to break down. i am now forced to switch just so i can use the internet. also side not if there was ever a way to get themes on mobile browser that would be nice.

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!

I tried it, it loads through EDGE, but through yours, if I enter it into the search, it loads at 70%, but the page still seems to work, albeit slowly. I didn’t have such problems with EDGE

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
