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.

Whenever I sign in to sync my browser it keeps asking me to sign in again to reconnect to sync.

I've tried reinstalling the browser, deleting the Mozilla directory in %APPDATA% and reinstalling, removing account and signing in again.

No matter what I do I keep getting asked to sign in again to reconnect even though the initial sign in was successful.

Helo team, I think I hit some key and firefox settings changed. I see squiggly characters in menu options, bookmarks etc.. Web pages load all right. I tried uninstalling/reinstalling. It did not help. Please see attached screenshots. I use a Mac M1 mini.

Be descriptive. Saying “playing video on YouTube is always choppy” will help us understand the issue better than saying “something is wrong” or “the app is broken”.

So, today i opened up my firefox and loaded up youtube; it didn't load. I tried to check my wifi speed on speedtest by ookla...the website didnt work. Then i went to reddit to see if this was a bug affecting everyone anddd that also did not work. So, basically half of the websites that i use do not work right now and i can't figure out why. Everything was fine till yestderday and i havent changed any settings. Also, Wifi speed is not the problem here as i opened up ms edge and everything works.

Please help! Here's a reference image of how websites look ( imgur ) Funnily enough, imgur also did not work of mozilla.

The bookmarks sidebar disappearing is creating inconvenience and I´m always having to use CNTL-B to recover it, even after I have selected View/Sidebar/Bookmarks which has a tick. Each time I change sites it deletes the tick.

I checked the about:config toobars and I cannot find it, or am I in the wrong place ?

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.

I have had it up to here with Firefox. I am madder than a hornet. Currently, I am unable to access my Outlook email and DirecTV in my Firefox browser, though I can in other browsers I have. Sometimes, I can't even sign into Ebay.

The DirecTV problem goes back at least 4 years to a different PC, so I have had this same problem on two PCs, therefore it can't be my PC. Besides, why can I access DirecTV on my Norton private browser and not on Firefox? I get the following error window:

    An error occurred while processing your request.

    Reference #219.b2173e17.1724008787.36e807

    https://errors.edgesuite.net/219.b2173e17.1724008787.36e807

The differing Outlook problem has popped intermittently over the past few months, but has happened more often lately. In that problem, the sign-on button is not activated.

Similar with the Ebay sign-on problem, except Ebay thinks I'm a bot and won't let me go any further than that perplexing error message.

I'm in the process of gravitating to the Norton private browser. I've already got all my bookmarks moved to that browser. At least Norton works for these three websites.

To put it bluntly, I think Firefox is a big stinking pile of horse manure. Firefox makes it EXTREMELY difficult to find out solutions. I believe Firefox actually WANTS it to be difficult to use. Why else would it be so hard to find out things? For example, instructions tell me to do something in some menu or click on some button, but the menu selections or buttons usually aren't there. I go round and round through the same blankety-blank webpages. I feel like a June bug constantly circling round a light. Even wanting to simply restore Firefox to original settings requires pulling eye teeth.

It took me over an hour to finally restore Firefox settings yesterday, which fixed things for THAT DAY ONLY. Today, the same problems cropped back up again.

I've had it. Unless I'm given some solution THAT ACTUALLY CONTINUES TO WORK, I am quitting Firefox.

Have a good day. I sure as hell haven't.

I am using Mozilla Firefox Developers Edition for Windows 11. Recently I have encountered a problem where my bookmarks are constantly disappearing from the panel and toolbar elements are changing places (like the arrows or the reload button).

I read the support and came across three articles about problems with this. The first two were xulstore and Places.sqlite files, which I deleted and followed the instructions in the article, reset the browser settings, but nothing happened. The third article was about the profile, I went in and saw that I had two profiles, which I deleted and created a new one, completely previously removed the browser from the device. But again, nothing happened.

I think this started when I started using the built-in Windows 11 workspace feature (multiple desktops, I opened two browsers at the same time). It was after this that my bookmarks and toolbar changed in the pre-login in the application.

I would appreciate help with this issue.

Hello all,

I just received my new Windows 11 computer and I'm setting up Firefox to my liking. I have sync turned on, but some of my settings didn't sync, (possibly because none of my other PCs are turned on?). Anyway, that's not the issue I'm writing about; I was checking the DNS over HTTPS to see what the setting was. The status showed "active" and the setting was set on "default protection".

I changed it to "max protection" but later decided to switch it back to default protection. When I did, the status now showed "inactive". I switched it back and forth between max and default, and the status change from active to inactive each time.

I read that DNS over HTTPS can show inactive under the following conditions: Firefox detects errors or certain network conditions like VPN, parental controls, enterprise policies that tell Firefox not to use DoH. I have a VPN turned on, but it is only active when I'm connected to an unsecured network, and the on/off toggle for the VPN shows "turn on", indicating that it is off and waiting for a network that has a weak security key.

Did I mistakenly think I saw active when it was actually inactive when I first checked the status of the DNS over HTTPS? Any assistance would be greatly appreciated.
