Firefox Support Forum

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.

Chrome and edge have "apps" that let me make websites into separate windows and treat much like apps. I can do this for my calendar, notes, and timer websites, for instance. I have yet to find a feature like this for Firefox. Does it exist? Is there a roadmap where this is being worked on?

Thank you

I am really struggling with Firefox after many years of MS Edge & its forerunners. When there is not an envelope icon on a web page, how do I share to email?

Hi, I have an issue with making the separators in the bookmark toolbar drop-downs visible. I am running Firefox 95 with the Quantum - dark Blue theme installed. I am running Linix Mint Uma.

The dropdown have separator - space - but no line showing that there is a separator. I have tried many ways to make the separators visible and with light-grey colouring in the userChrome.css file but nothing changes.

Anybody have any idea what can be done or where I might change the Quantum-DarkBlue coding to incorporate the visible separators?

The font size in the toolbar is too small. I mean the text on the tops describing my open tabs, the bookmarks toolbar, etc.

I cannot find an actionable answer to how to increase or change the font size. I need a solution, but not written in a tech language. Is there one?

I disable my option "Restore previous session" and it works fine if i close my firefox.

But if i do not close my firefox and reboot my computer directive, the session will restore at next startup.

Obviously when i reboot my computer, I don't want to see my tabs anymore, but I failed to find any setting to do so. I also find someone say to set `browser.sessionstore.resume_from_crash` in `about:config`, but it doesn't work, and I don't think it is the proper way to solve this problem because reboot is not crash.

I learned that Firefox has pdf editor in the new version but I can't locate buttons to edit/fill a pdf document. I tried to search that on the web but could not find those. Would you please send me the tips on how to use this feature? Thank you.

Hi, I'm migrating to a new PC and followed the below article to open all my currently synced tabs from the old machine on my new one: https://support.mozilla.org/bm/questions/1357426

The issue is that the on the new machine when I open all synced tabs, the order is reversed, i.e. my latest tabs that are on the right on the old machine are now on the left in my new machine. How do I tell open all tabs to keep the same order in the new machine? Any help is greatly appreciated..!

Thanks! manoja

Dear Sir or Madam; I downloaded a login CSV file from the Firefox browser. The date columns format in the CSV login file is ‘1.64055E+12’. In EXCEL, 44556.79166 would translate to 2021/12/26 18:59:59. The translation of ‘1.64055E+12’ should not be the same exact date, but should be in the same date range, as the 44556.79166 number. I’m not a mathematician. Would you please show me how to convert the '1.64055E+12' value to an equivalent excel date/time number? I could then format the excel date number cells to an yyyy/mm/dd hh:mm:ss format. These scientific number values are in the Firefox login file CSV downloads so I assume they were intended to be used in EXCEL spread sheet. These values converted to EXCEL date values would help me sort account password date change records by account name and change date. I could review sorted account records (and thus determine the current password for individual old accounts). Your solution would help me immensely and I appreciate your time.

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.

Hi Firefox,

A site I visited recently moved to another URL. Is there a way to edit my browser history so I can still be able to keep track of which pages I have visited?

For example:

if I have visited

https://site-old.com/topic1/page1.html https://site-old.com/topic1/page2.html

I want my browser history to also contain

https://site-new.com/topic1/page1.html https://site-new.com/topic1/page2.html

So I can see that I have already visited the page1 and page2 on topic1 as the link color would be purple

Would I be able to script something in a developer console and achieve that? Or would I need to program a plugin?

thanks!

When installing Firefox, there is an option to import data from another browser. That feature is also available in the "Library -> Import and Backup -> Import data from Another Browser", and it imports things like Bookmarks and History from another browsers.

As the functionality already exists, is it possible to use that functionality in any way to import Bookmarks and History from a different profile in the same Firefox installation? I want to merge 2 different browsing history (like the old question https://support.mozilla.org/en-US/questions/928204), and looks like using the "Import data from Another Browser" could help if it's possible to use it with another Firefox profile/directory.
