Firefox Community Forum

Steps to recreate:

1. Open any website
2. Make any css changes. These will be shown in the Changes tab in the dev tools
3. Close dev tools, then re-open. Now those changes won't be shown

Sometimes I need to close dev tools in order to see how the web page would look normally.

Hello,

I have been experiencing this issue for a while, but only just now noticed it. When I hover over a tab, nothing shows up; no preview, no title, no web address, nothing. I have a few extensions, but uninstalled any that would effect tabs at all, with no change. All other extensions I have had since I switched over to Firefox. I have attempted to search for solutions, and have followed what I found. Multiple support questions here have gotten the answer of going into the config to change the following Boolean variables to be true:

   browser.tabs.hoverPreview.enabled 
   browser.tabs.hoverPreview.showThumbnails 

but when I went to do so, they were both already set to true. I disabled and then re-enabled them just to check, but nothing changed. I have a ridiculous amount of tabs open, but that's the only other thing I can think of that would be causing this issue. Just in case, I am in the process of closing as many as I can.

Any advice or assistance would be appreciated.

Thank you.

Hello.

In about:config the keyword.enabled false does not work anymore.

So how on earth do we stop this stupid search option in the url bar. When i open a new tab, i'll get on a firefox tab. In the middle I can search (in the search bar), but after typing 1 letter, the search is moved to be in the address bar. WHY????

How to stop this madness?

Thank you for an answer

Why is there in about:config no reference to documentation of the displayed settings?

e.g. browser.chrome.toolbar_tips.hide_on_keydown

What is it? What is the meaning of the values? What is the default value? Why do we have to guess?

It is probably documented somewhere (I hope). Why is there no reference to it in about:config?

Hello,

I have an issue where, when I switch tabs with Ctrl+Tab, my mouse cursor accidentally triggers something if it happens to be in the center. This is very annoying. I tried Googling how to turn off tab visualization through the config, but it hasn't worked so far.

   * browser.ctrlTab.previews

• browser.tabs.closeWindowWithLastTab
• browser.tabs.animate
• toolkit.cosmeticAnimations.enabled

So now, the only option I see is to turn off Recent Tabs, but then the browser becomes unusable. I also tried the same on a new clean user profile and even on new Mozilla-based browsers, but still nothing. It would be ideal to make the cursor inactive while switching tabs, like it is in Arc Browser and probably many others. But I would be happy enough to just turn off tab switching visualization.
