Firefox Support Forum

Hello Mozilla Support Community,

I'm an aspiring web developer diving into the world of Firefox add-ons to enhance my workflow. While I'm familiar with some popular add-ons like Firebug and Web Developer Toolbar, I'm eager to explore more tools that can streamline my development process further.

I'm particularly interested in add-ons that aid in tasks such as:

Code Editing: Are there any add-ons that offer advanced code editing features within Firefox, such as syntax highlighting, autocomplete, or code snippets management?

Page Inspection and Debugging: I'm looking for add-ons that provide robust tools for inspecting and debugging web pages. Something akin to Firefox's built-in Developer Tools but with additional features or customization options would be fantastic.

Performance Optimization: Are there any add-ons geared towards optimizing website performance, such as identifying and resolving bottlenecks, analyzing page load times, or minimizing resource usage?

Cross-Browser Testing: I'm curious about add-ons that facilitate cross-browser testing within Firefox, allowing me to preview and debug my web projects across different browsers without leaving the browser window.

Accessibility Testing: Given the importance of accessibility in web development, I'm interested in add-ons that assist in testing and ensuring web accessibility compliance.

Version Control Integration: Lastly, I'm wondering if there are any add-ons that seamlessly integrate version control systems like Git or SVN into Firefox, providing convenient access to version control features directly from the browser.

If you have any recommendations or personal favorites in these categories or any other add-ons that you find indispensable for web development, I would greatly appreciate your insights. Thank you in advance for your help and expertise!

Using Firefox 108.0.2 with Windows 10 on an HP laptop and Thunderbird 102 current version.

When filling out a form and box shows enter email address there are times with saved email address pops up into box. I cannot find where those email addresses are located so I can add or remove one or more addresses. Where are those address stored? Thanks

Hi, I discovered that in order to achieve that, you set in about:config "permissions.fullscreen.allowed from the default false to true. The default behavior does not stop the video with a single left mouse click, but triggers full-screen. It would make sense to make "true" the default as it seems more intuitive to control both the play and full-screen in that way.

How can I translate my website https://rhizmall.pk/ in Mozilla with different languages, like other browsers shown by right click on tools bar or on web page to translate in different languages?

I need to transfer cookies - and ONLY cookies - from one Firefox profile to another. Copying the cookies.sqlite file did not work - none of my preferences or logins were saved on the new profile. How can I copy all my cookies to a new profile?

Title is self explanatory. When I try to take and save a screenshot in my browser, either when right clicking and selecting Take Screenshot or using CTRL + SHIFT + S it always cuts off some of the image I'm trying to take. Any ideas on how to get this fixed?

Every time I right click and select "Open Link in New Tab" Firefox is not opening this new tab next to the current tab. It instead moves this new tap to the end of all the tabs (of the current website). This is an annoying behavior, I have to go all the way to the end of the tabs to look at the name page that I just opened. How do I fix this behavior?

I have always had this option with Chrome and other browsers. But I can't find this feature in the latest version of FF.

I want to disable images on specific websites, not all websites. I examined my address bar and there's no option there at all when I'm the specific site I want to block images and/or media.

I have searched for "How to share tabs between profiles" in firefox.

I was offered this option:

Share multiple tabs

   Visit the tabs tray by tapping the number next to the address bar, this number shows how many open tabs you have:
   Tap the three-dot menu button in the tabs tray.
   Select Share all tabs.
   The list of tabs to be shared will appear.

Visit the tabs tray - not very clear. by tapping the number next to the address bar - which number? I have more tabs that can fit across the screen and am not seeing any number/s.

Could someone help me with this please? I have a lot of migration to do.

While hovering over a Youtube video it shows the full video title as "hover text" if the tab is focused. However, if something else, even another Firefox window is focused hovering no longer shows anything. Is there some kind of setting to change that? I figured it could be browser and Youtube specific because Chrome shows it on Youtube even when not focused, but neither browser shows it on Google search for example, but I'm not sure.

The latest version of Firefox I have keeps making changes to my computer every time I open the program. I have to approve the changes each time, why is the program suddenly doing this? What does it have to change on my hard drive? I don't like programs making changes to my computer when they open they are usually not to my benefit and add clutter to my computer. Please answer, so far no replies to any of my questions!!

Why doesn't Firefox Browser have collections? I have both Firefox in Beta and Firefox Browser on my Android cell phone, but I prefer using Firefox Browser, although I do like the collections feature from Firefox in Beta.

Does anyone know the reason?

Thanks, Marianne

Audio has stopped working in Firefox only. Audio is working for Windows/PC system alerts and playback in all apps and browsers except Firefox. Perhaps after a system update....I'm supplying the answer to this in replies. I had to re-ask the question because previous versions of it with incomplete solutions have been archived and do no allow more input. So, yes, I'll be answering my own question. Just for you. XXOO

FF 115.02 Win11

I fill in many repeated responses, such as DOB, zip code, etc. I was using Edge for a while and have forgotten the benefits of FF. Does it remember? Can I edit or delete the ones that are no longer relevant or have changed - age, for instance?

Thank you.

Hello, I've got two profiles, 'Home' and 'Work'. I run two Firefox windows with these profiles. Now, I want to open a link from another application, like Slack or terminal, and want it to be opened in some predictable Firefox window. Now it depends, probably, on which Firefox window I opened last. So I want to be able to select in which window the links should be opened: I see it as marking a window as the default one. Note, that I don't want to set a default account, as there's no default account for me, I always choose which account to use when opening Firefox.

Thanks.

Some webpages cause the browser to automatically reload them at periodic intervals. Sometimes these intervals are too short and in the middle of reading the webpage it gets reloaded.

How do I prevent Firefox from accepting a reload command from the webpage I am currently browsing?

I did not see an answer to this in the FAQ.

Thanks in advance for taking the time to read this and answering if you choose to do so.
