To optimize performance and ensure cross-browser compatibility in complex web applications, several best practices can be implemented:

   Use Responsive Design: Employ responsive web design techniques to ensure that your application functions well on various screen sizes and devices. This approach enhances user experience across different platforms.

   Minimize HTTP Requests: Reduce the number of HTTP requests by combining files (like CSS and JavaScript) and using image sprites. This can significantly improve loading times.

   Leverage Browser Caching: Implement caching strategies to store frequently accessed resources, which can speed up load times for returning users.

   Test Across Multiple Browsers: Regularly test your application on various browsers (like Chrome, Firefox, Safari, and Edge) to identify and fix compatibility issues early in the development process.

   Optimize Images and Assets: Use appropriate image formats and compression techniques to reduce file sizes without compromising quality, which can enhance loading speed.

   Utilize Best Application Development Services: Partner with experts who provide the best application development services to incorporate performance monitoring and optimization tools into your development workflow.

By following these practices, developers can create robust applications that not only perform well but also deliver a consistent experience across different browsers. Engaging with the community to share insights and experiences can further enhance our collective understanding of effective application development strategies.

We deploy Firefox via a software called Pulseway and last night it reinstalled Firefox over the current installation for one of our users. When he logged in this morning, all his data was missing from the browser as it appears to be a fresh installation. I'm unable to find his previous profile in the AppData folders (checked by going to about:profiles and opened each profile). There is no backup for this info, and he did not have a Sync account set up. Is there anywhere else I could possible recover this data for the user? Thanks in advance.

Hi, I'm using Linux Mint 22, Firefox 129.0 (64-bit). Browser is hanging after approximately 4 hours. Not sure if this is a Firefox issue, but this is where I'm starting the troubleshooting process. My suspects are (1) the browser, (2) NVIDIA drivers (3) the new Linux Mint kernel or possibly (4) a mix of the above. This was a fresh install with default options on (Wilma). Using the latest graphics drivers for GeForceRTX 2060, driver version 555.58.02, went down to native drivers, no change. Honestly, this one has me baffled. Been troubleshooting this for 3 days. It feels like a memory leak. Nothing on the crash reports. First, browser will hang, then mouse and keyboard. Hard reboot is the only option. Any help would be appreciated.

When i do update my configuration settings changing by itself. Example, "browser.cache.disk.enable" is "false" but after every updates its always changing to "true". This happens only after updates.

How do I change the google account that Firefox visits first? Context: I have my work email set up for sync, but whenever I go to any google specific site or tool (Calendar, gmail, docs, etc.) it defaults to my personal account instead of my work account.

I've had trouble with this in the past where logging into Ring won't let me get past my user name/email address. I can hit enter, reload the page, try using tab but nothing works. Then for some unknown reason it will go forward to the password. But this time it just won't let me proceed no matter what I do, the continue option stays grayed out. I can sign on using Edge but I don't want to use Edge or even have a second browser open just so I can see my security camera. I want Firefox to work correctly.

If you are currently using a normal window then there are ways to open a bookmark or link in a private window. But if you are currently using a private window then how would you open a bookmark or link in a normal window?

I have tried several things including pressing shift+enter or choosing "Open in new Window" from the context menu, but this just opens the bookmark or link in a new private window.

My current method is to copy the address of the bookmark or link then paste it into the address bar of a normal window.

But is there a more direct method of opening bookmarks or links in a normal window, if currently in a private window?

Thanks.

Hello. How can I post HTML code snippets in support.mozilla.org questions ? All HTML code is rendered and none of the usual markdown (``` etc.) works.

This topic appears to show up a few times, but none of the solutions work for me (e.g. they were using A/V or "it just worked"). The error I get is also different.

This a pretty fresh install (migrating from Chrome so I'm currently re-logging into all my sites to ensure I can access everything I need.. and going through MFA hell heheheheh).

Everything is mostly fine, except for Synchrony Bank.

I go to login at https://auth.synchronybank.com/account/login, enter _any_ username or password (doesn't matter if I enter the right details or the wrong ones), and as soon as I click "sign in" I get an error page

Looking in developer console, the error reason given is NS_ERROR_NET_INTERRUPT while trying to POST to auth.synchronybank.com. Every so often I get PR_IO_TIMEOUT_ERROR but over 90% of the time it's NET_INTERRUPT.

This occurs also in private browsing and also in safe mode. I even created a new profile and tested it from there; same issue.

I've tried lots of things related to this (e.g. setting network.http.http3.enable to false), added the domain to the advanced tracking exception list, and I'm running out of ideas.

I can see traffic flowing to akamai but (it being https) I can't see what's inside the traffic. Could akamai be objecting to something in the content?

FWIW, I can login with Chrome on the same machine.
