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.

In the previous version of Firefox I could install a multiple language keyboard layouts in the upper right row. I had to reset everything with a new HDD and Ubuntu 24, which comes with Firefox for Linux as well. Now I can't find how to install those shortcuts that I had before. I need to use Slovenian, Italian, Spanish, German and US keyboards (UK is standard with UK English as primary choice). Thank you for your help.

After an update of both macOS (to macOS Sequoia 15.0.1) and Firefox Developer Edition (to 132.0b3 (aarch64)), the Bookmarks Toolbar stopped working. The same issue appeared on my Windows PC.

Bookmarks toolbar is visible, I can show and hide it but it does not display any of my saved bookmarks. Luckily, they were not deleted and I still can access them via Bookmarks Menu, which is less than optimal.

The Drag&Drop functionality does not work either. When I grab the opened Tab, drag it on the Toolbar and release it, the Tab gets opened in the new browser window and it's not saved.

I have been unable to sign in to google accounts on 3rd party websites for a while now. I'm using firefox develloper edition. i do not have this issue with normal firefox

every time i try to sign in i get redirected to https://support.google.com/accounts/a.../32050?hl=en

Heres some of the things i tried:

• Clear cache and cookies
• "repair" Firefox from the uninstaller
• Reinstall Firefox

To be honest it is quite a bit annoying and i cannot find a solution thanks in advance for any help

Hello, this is josh, I have a dedicated website for my business and I use Firefox Brower. The problem i'm facing right now is the website isn't loading properly in the Firefox. Website isn't showing image and proper site. However, when i try to open the site in the other browser, it looks fine. what should I do, you please guide me.

Firefox is, without a doubt, the best browser I have ever used, and I mean it. It's privacy oriented, great GUI, and is overall customizable. But, there are definitely some things which need improvement ASAP, such as the following: When I mouse over the top of my screen, Firefox semi-exits full screen mode and displays the toolbar. It is extremely annoying. Please make this an option somewhere; for me, even a hacky fix will do. Please, just help me get rid of it. Thanks :)

I'm having much difficulty in attaching a article I see to Facebook. Its possible the problem may be I'm not using the right instruction on the Firefox options when I right click the article I want to attach to Facebook. Some of those options are, Save link as, Copy link, when I right click for options. Can someone explain what is the right option to use? And, how do I proceed once I choose the correct option to make that attachment to a Facebook message I'm replying to? There are times a picture of the article will attach to the Facebook message, but the text that is associated with the attachment will not appear? Can someone please help? Thank you.

Hi all,

I'm using Firefox 125.0 (64-bit) on Fedora and for file downloads, I have the options "Ask whether to open or save files" and "Always ask you where to save files" enabled.

This basically works, Firefox opens a file selection dialog and I can select where I want to save my downloads - so far, so good.

The weird thing is, the default location that is shown in this dialog seems to change every time I download a file. I would expect to see the last download location as the default option, but that is not what happens.

When I check about:config, I can see the last used download path is saved as browser.download.lastDir perfectly fine, but it is not set as the default for the next download.

Is there a parameter I can set so this last path is used again?

Thanks,

M.

I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

When visiting a site with a Input=Number field and clicking on it and scrolling nothing happens when it should change the value as if i had pressed up or down arrow.

I thought I had solved this by adding the website to the "safe" list - I really cannot say how frustrating this is if I am being locked out of even safe sites. - This is a browser issue (I'm not that naive).

There is no real response from Moacilla(Firefox) here apart from throwing the Rulebbok at me and saying "Read!". I can only do so much Tune ups" and shut downs and ensure drives are functional. Please advise on the Browser Cache situation, rspecially as BBC iPlayer is added to the "Safe List" and yet still throws up the 400 Bad Gateway error message - an early reply would be useful.

I have a suggestion, could Alt + left/right arrow switch between tabs that are next to each other? This shortcut is e.g. in PyCharm and I think it would significantly improve my browsing experience. It seems to be currently unassigned.

All my bookmarks and toolbar are gone after you forced me to upgrade firefox. YOU CAN HELP ME BY NOT FORCING ME TO UPDATE AND THEN DELETING ALL MY IMPORTANT BOOKMARKS AND THEN ACTING LIKE YOU WANT TO HELP ME BUT INSTEAD WASTE MY TIME WITH ALL YOU JACKOFFS THAT ACT LIKE THEY KNOW THE ANSWERS. FUCK YOU YOU IM DELETING FUCKFOX AND GOING ELSEWHERE, I HOPE YOU ALL FUCKING DIE
