I want to programatically access the open tabs #document object by the Browser Console. I am in chrome://browser/content/browser.xhtml I fallow the docs in browser console: https://firefox-source-docs.mozilla.org/devtools-user/browser_console/index.html

Following the code: var newTabBrowser = gBrowser.getBrowserForTab(gBrowser.selectedTab); newTabBrowser.addEventListener("load", function() {

this page has been eaten

}, true); newTabBrowser.contentDocument.location.href = "https://mozilla.org/";

.contentDocument is null except if current tab is a page such as page about:config

Is there a way to allow chrome:// tab to access read only of the tabs #documents property using the console?

I understand that accessing it with javascript from the browser console would be a security issue. I want to bypass it to read, analize and compare dynamic data from the open tabs.

My configuration is the following: Windows 11, internal display connected to iGPU and external UHD display to nvidia-HDMI port, multiple firefox windows are opened (1 one the internal screen, 2 on the external).

Then in Windows->Settings->GPU I can select firefox to run on either iGPU (powersaving) or on Nvidia GPU (max perf), the problem is the following: Whenever I set firefox running on iGPU, there would be a massive stuttering/framedrop on an external display (connected to NVIDIA), while a perfectly smooth browsing on internal display, and vice versa.

My first attempt was to disable webrenderer compositor or switching it to a software rendering, which fixes the heavy stuttering, but the scrolling becomes overall less fluid/responsive.

However, setting "layers.gpu-process.enabled" to "false" seemingly solves this problem completely. Now I have a perfectly smooth scrolling on both displays, regardless of which GPU is used in Windows->Settings->GPU (nvidia's is arguably a little but more responsive).

Hope this helps someone, or maybe dev team could look deeper into this.

Thank you for the great browser!

I would like to be able to quickly identify certain URLs that appear in my Firefox history by simply looking at corresponding icon — is there a way to edit a Firefox history item to do this?

I have Yahoo.com as my email provider (Firefox is my internet provider). When I get emails I don't want, I move them to the Junk Email option BUT, it only deletes that specific email and does NOT keep it from being sent again (and they ARE, repeatedly). I contacted Yahoo and and all they do is send me to a website that will answer the question but sign me up for a monthly $46 to $55 fee. Any way known that I can solve my problem?

Hello, I faced such a problem as a very strong contrast on all videos, for example on Youtube. I used firefox 2 years ago and there was no such problem. I tried to reduce the brightness and contrast in the monitor settings, but alas it did not help. Please help me solve the problem

Is there a way to change text alignment for Firefox PDF viewer?

When I add text to a PDF file, sometimes it's left aligned and sometimes centered, so I think I might have changed the alignment accidentally.

Hi

I need to download Websites automatically via Batch exaktly like the Browser would save them via Strg+S.

I used curl to do that and it worked fine for many years but now the Source-Website has changed and so curl is no longer able to get the content. The problem is that the URL / Website that the Browser downloads does not contain the information. This is loaded later by a java script.

So when I open the URL in the Browser and look at the Source-Code I can see something like

 <script src="/example.js"></script>

When I press Strg+S to save the website the whole site is saved, because the java script was executed by the Browser. Curl does not process java so it saves only the source code with the "<script src="/example.js"></script>"

Question is: How can I download the URL directly with the Java Script executed so that the informaion is included too ?

I hope anybody can answer that.

Thank you.

I have previously been able to include the tab 'Close Tab' item in the #contentAreaContextMenu by adding it to browser.xhtml. This no longer works even though 'Reopen Closed Tab' and 'New Tab' still do.

     <menuitem id="toolbar-context-openANewTab"
               command="cmd_newNavigatorTab"
               data-l10n-id="toolbar-context-menu-new-tab"/>
     <menuitem id="context_closeTab"
               label="Close Tab"
               data-lazy-l10n-id="tab-context-close-n-tabs"
               data-l10n-args='{"tabCount": 1}'/>
     <menuitem id="context_undoCloseTab"
               label="Reopen Closed Tab"
               data-l10n-id="tab-context-reopen-closed-tabs"
               data-l10n-args='{"tabCount": 1}'
               observes="History:UndoCloseTab"/>

I was previously using the following which no longer works either.

       <menuitem id="context_closeTab"
               label="Close Tab"
               oncommand="BrowserCloseTabOrWindow(event);"/>
