I've been professional web developer for almost 15 years. I've wanted to try to step away from Chrome, but I'm having a hard time navigating through basic functionality with Firefox's developer tools. One of those was a simple "Control + F" find feature. Am I missing something?

Specifically, lets say I want to search for a specific class within a style sheet. In Chrome I can bring up the dev tools, select the style sheet, Control + F, and it will give me a toolbar with options to step through each instance of the class. It gives me total count and I can hit the up or down arrow to cycle through each instance of that class (insert any selector here). I can also Replace an instance or all instances.

When I try this in Firefox's dev tools, I get the first instance but see no way to do anything else. If I hit enter it doesn't cycle through to the next instance but creates a line break in my style sheet.

I've researched with no success. I know there is the filter option but that isn't what I'm looking for in this case. Any help would be greatly appreciated.

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

Firefox has inexplicably begun opening in a narrow screen by defalt. I want to set it to opening full screen by default. It's a pain to have to click twice or press F11 for full screen use. How please?

Using FF 108.0.2 (64-bit) in Debian 11 Linux,I need to view http://www3.winsystem.org/monitor/webmonitor.php but my new laptop is very high resolution. I can control the text size with Ctrl+ but the background gif image of a small window with bogus scrollbar needs to be made larger somehow so that the white text can be read against the black portion of the image.

Is there some way to enlarge the gif image, please?

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

What are the steps to add a URL icon to my home page on my laptop? I currently have two rows of icons for URLS for websites like: Amazon, eBay, Canadian tire, VirginMobile, etc., etc. I want to add Facebook to this group. How do I do it?

Hi firefox team

I think better to add sleeping tabs option-like edge browser-to saving resources of system. saving system of chrome is not ok. because offloading tabs. but, edge don't offload and its faster!

thank you all for creating best experience browsing. and sorry for my bad English grammar :)

My Firefox refuses to load MetaCPAN's OpenSearch.xml file, even though I can access it without problems.

So this got me thinking, as Opensearch files are relatively easy to write, is it possible to import my own opensearch.xml into Firefox?

If it's impossible, I'll submit a ticket to bugzil.la.

Hi there,

I have a laptop running Windows 10, plus the latest version of Firefox. The laptop has a built-in webcam. I have also connected an external webcam via USB. This second camera is better quality and preferred, I visit a web site. When I first activate the camera, I am presented with a dropdown of available cameras. The USB camera appears in the list. All is fine. I instruct Firefox to "allow" this camera to be used. (first image) However, after a short time, less than a second, the same dialog is shown again, this time without the USB camera. (second image) There have been no actual hardware changes. I can then click "allow" again and the *integrated* camera works, i.e. not the desired camera. So, two questions, really. First, what just happened? Did Firefox try to control the USB camera, find that it couldn't, and redisplay the dialog showing only the "controllable" option? Second, my desired endpoint here is for the web site to use the USB camera. How do I achieve this? I can easily do this with Chrome but I like Firefox. TIA.

I have to search for a lot of entries in a long page, click on them to another window, do something (fill in a syllabus) and then go back to the long page and change the next search hit.

When I return to the long page the search in page is remembering where I am in the number of searches shown at the bottom of the page (e.g. 19/34) but when I click on the down button, instead of going to 20/34 it jumps back to 1/34 so then I have to press the down button 20 times to get to the next search hit.

Is there any way around this, so that I can just jump to the next search hit without having to press the down button 20 times?

I thought it might be the fact that the search is off screen but that is not it. It is the fact that I have left the page so the focus has been forgotten (except as the number 19/34 on the search in page bar at the bottom).

Is this a bug?

Since this took me awhile to figure out I thought this could help other people.

firefox Did Not Connect: Potential Security Issue

Also you can manually add sites in preferences. Privacy & Security Preferences → View Certificates... → Servers → Add Exception

I realize that the page I am using findbar to search from reloads and scrolls to the top using some Javascript so that when I return to the searched page from a popup, the last search item is no longer focused when I come back so (or press F3 or Ctrl G) e.g. if I found the 29th hit, then I have to click down 30 times to get to the next search hit.

I tried using add-in Luminous to disable the reload/scroll to top of the page that I am searching but failed. It is a complicated add-in.

Is there any way to jump say 10 hits down at once?

I've been making my own Firefox theme using the Firefox Color extension. I uploaded an image but I can't figure out how to show the image on the new tab screen. Setting the new tab page color to transparent only makes everything white. I know the image is uploaded correctly because I can see some of it in the toolbar and tab list. Is it possible to show the image on the new tab page?

Hello! (sorry for my English in advance)

I frequently visit this website <mi.tv>, which is an online TV guide, to see what's on TV today, but the movies rerun TOO MUCH among the channels, making me always pass by the same movies everyday, again and again... So, I'd like to know if there's a way (JavaScript, CSS, some add-on, etc.) that allows me to hide some of the entries from the movies list (the movies I will never watch), and make the changes permanent. I've tried to use the Inspector, but, although I could manually hide some entries, it (obviously) didn't resisted a refresh, so I'd like a permanent solution, where I can mark a movie as "won't watch" (or put it in a list, or something), and it will be hidden in the site forever. I'm attaching two images, to show how the site is normally, and how I've hidden some entries using the Inspector (red arrows).

P.S.: this site has even an Android app, which is way more practical (in my opinion) than the site, but to ask for an Android solution would be too much, I think =D Anyway, it'd be already great to have a solution for this in Firefox Desktop!

Thank you in advance!
