I'm inspecting an element and when I use the 3 dot menu and search, it shows me results in sources tab. I try to edit the result, but it won't let me edit the sources tab. It only lets me edit in the elements tab. How do I search the elements tab? It keeps sending me to sources. It would be great if sources was made read/write as well. Many thanks.

I live in the sticks and get my internet via satellite. Sometimes it's acceptably fast and I can watch a video, not live, but after only a short wait to download it.

I have Tranquility Reader extension, and this is very useful. But whenever possible, I'd like to be able to see images, ads, and whatnot. Is it possible to automatically activate an extension, this extension, when my download speed is less than 10Mbps.

Can this be done currently? If so, how? If not, would you be able to notify me if this feature is ever added or something similar.

Thank you, Charles Smith Murphy, NC

I continued reading on FireFox, and found that there is a "Refresh" procedure that might work, AND IT WORKED!

I'm so glad. Thank you. Of course it brings up other issues that may need attention, unrelated.

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!

Hi everyone! I am organizing a school event in which we will have a large group of people watching a livestream of the 2024 OSCARS on a big projector. This will be a free event to students, so we are not profiting off of attendance. We did this last year, but ran into difficulties as the projector screen turned black, and then when it did start working it would be without sound. For this year- Will firefox allow for this Oscars event to be streamed and transfer to a projector?

Thanks!

On my Macbook air (m1 2020 14.3.1 (23D60)) /etc/hosts is ignored by Firefox 123

i've tried multiple offered (old) solutions from stack but non work.

FAILED ATTEMPTS:

• DNS over https -> off
• network.trr.excluded-domains ... tried to add the domains in the dns over https exeptions ... didn't work either
• added the domains to network.trr.excluded-domains
• cleared cache
• restart ff
• migrating all my /etc/hosts config from multiple domains on a single line to separate lines did. Hope this helps someone.
• network.ttr.mode = 5
• sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder in the terminal

Background: I run my own server and I cannot access them over the internet if I am on the same network (rounter dissallows this) This is annoying as I cannot develop via my laptop.

/etc/hosts is changed and in the terminal all (ssh etc...) works fine.

What is the proper way of doing this these days?

I have Yahoo.com on my desktop which takes me to my email account. I would like to get it on my task bar but when I try and move it down it is adding it to Firefox on the task bar. I can't seem to get it down there to stay

I am visually impaired and I need the Fonts to be Bold. I have changed the font and size but I can hardly read them they are so light. Especially on the Book mark page.

Up until now, when I've downloaded a file, the download button displays a dropdown of the downloaded file list, and other features. After updating to v104.0.2, the download button ONLY highlights to signal that files have been downloaded to my download directory, but clicking this button does nothing. Instead, the only way I can access my downloads is by Ctrl-J or clicking on the 3-horiz-lines and select Downloads, which opens a separate dialog box. Why this change? How can I restore the old/standard feature which worked quickly and intuitively?

Hello. For some time, under each entered expression in the sent post office there has been a red "wavy" underlining. The problem is to choose a language. In my case it is Polish. Unfortunately, in the Firefox browser, which I use, there is no option to change the language to Polish (Annex 1) as it is in the Google Chrome browser (Annex 2). Why? I would like to add that this phenomenon only occurs in the case of Onet in Firefox. How can this be removed? Regards Alex.

Hello everyone,

I need to recover a web page that I visited several times last fall using Firefox on Mac OS. I have regular backups which should include the Firefox cache files, but after looking through several threads online it is not clear exactly which file I would look for in my backups, and how I could go about actually looking at the cached version of that page. I have seen some tools for viewing old cache files, but the only one that seemed reasonably easy to use is only for Windows.

I would be grateful for any step-by-step instructions on how I can see an old page (or at least any parts of it that were cached) that no longer exists.

Also: I tried the various internet archives such as way back machine and google cache but no such luck. This was an ad on a real estate website in Italy.

Thank you in advance.

Firefox 104.0 64-bit

I hid a photo on a webpage to see if its space would collapse and bring the text closer toger so I could make a screeenshot. I right-clicked on the photo and selected "Block Element". The photo disappeared, but the space it had occupied remained (outline of photo, filled with background color). I right clicked in the space, but there was no "Unblock Element" to select.

I looked online for an answer to this question, which seems not to have been addressed specifically. One of the results suggested using an add-on called Firebug; another suggested uBlock. I guess another question I might ask would be, why would it require an add-on to unblock an element that was blocked using Firefox?

It is not vital that I get the photo back, as I can contrive to never visit that particular webpage again, but my inquiring mind wants to know how to unblock an element I have blocked—particularly since it was so easy to block it in the first place.

Thank you.

Since updating, "Exit Full Screen" now causes viewed page to become a narrow sliver at the top of the screen, and the page unusable. I typically drag pictures from my desktop to Facebook, etc., but can no longer do that. (I know there is another way to access pictures from the desktop, but it is currently unreliable on my machine, which is very slow and wonky right now.) Can I revert to the former function where "Exit Full Screen" just makes the page smaller but still usable?
