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.

Speedometer2.1 My Firefox Score: 161 My Chrome Score: 380

why im missing? its normal? same hardware, no extensions.

how can i increase my firefox score?

i have Ryzen 5600 CPU and Radeon 6600 VGA and M2 SSD

In Chrome, I can hit CTRL+SHIFT+I to open developer tools, add the Media tab, and go to the Media tab, and I can see the codec and what decoder is being used.

How do I do the same thing in Firefox?

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'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 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 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.

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.

When opening pdf's attached to emails they used to automatically be opened by my pdf viewer software. Then they started opening in Firefox on another tab, which was fine. Now I first get an error message from firefox where I need to click on "open site in new window" it isn't a site but a pdf?? How do I get it to go back to opening with Adobe instead?

Thanks, Jeff

My Windows PC apparently crashed when I tried to Hibernate. I knew this because when starting up the PC state was not persisted. I started Firefox (v97 x64) and it would not load any websites. The about:config page loaded.

I was at a loss as to how to resolve this as I could find no advice for this problem.

I thought I would try Safe Mode. Unexpectedly, just starting in Safe Mode resolved the issue without doing anything else. I am now back to normal.

I'm curious to know what just starting in Safe Mode did to resolve the issue. I also want to broadcast this as I did not find this as a potential solution.

Don't comfortable search results issue. I'm nervous about, get a result and than show another many issue. That is no need for us. why show it? example image below.

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?

I configured my Windows 10 Firefox proxy to use system proxy settings, and I have a script can based on different network environment modify the system proxy autoconfiguration script address (HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\AutoConfigURL) in registry to update the proxy settings. Internet Explorer works well - new proxy configuration usually become effective in 1 or 2 minutes after the change. However, each time after my script changes the registry proxy address (without FF restart), I have to go to Firefox Tools->Settings->Proxy to manually change it to another value (in my case it's from "Use system proxy settings" to any other value), confirm it, and then change it back. Then FF is able to reload the autoconfiguration script to make it work. This is really a headache.

I just wonder is there a way to notify FF to reload the proxy autoconfiguration script address from registry from command line so that my script can trigger it automatically after the registry is modified?

Thanks.

I remember long ago on an ancient browser there was an option in the print dialog to print a table of the links on a web page. Very useful for a page which has a lot of in-line links but no 'references'-like list of them all at the end. This can painstakingly be done by copying and pasting from the source code, but... years later, do we really not have a better way, like we used to??

Okay so basically for example lets say i want to permanently just for my screen have this image deleted/or hidden whatever how can I do this without using an extension?

I believe someone brought up usercontent.css?
