I've been having issues with Cross-Origin Request Blocked errors for a while now. I'm on Windows 11. I first noticed this issue when visiting YouTube. I would go to play a video and any video I tried to play would just load forever and never play. Then I noticed I was having the same issue on Facebook. The page would load but then a majority of the images wouldn't. I can use YouTube and Facebook just fine on Chrome. The reason for the error shows as "CORS request did not succeed". Initially I tried uninstalling all of my extensions. Then I completely uninstalled Firefox using Total Uninstall (for good measure). Nothing has worked. I'm not sure what changed that would cause these errors. Could this be a network issue? I've been having issues with certain sites on my Macbook Air as well (Chrome and Safari) but I thought maybe that was because it's pretty old and not supported by apple anymore.

Youtube's side panel on the left does not load at all, the videos on the homepage do but none of them can be played. When I play a video the website doesn't load that either. I only get an hourglass icon on the tab. Image attached.

Google search results don't show up immediately, despite being loaded. Only after about 7 seconds. Image attached.

I don't have this issue on other browsers. It has only started occurring 3 days ago, I'm clueless as to what the cause may be.

Solutions I have tried: 1. Restarting my PC. 2. Turning off all my extensions. 3. Running Firefox in troubleshoot mode. 4. Refreshing Firefox.

Hi All,

I need open local exists files

file:///.../index_details.rst or file:///.../index_details.txt in my default system editor.

This has worked pretty well last in version 127. (https://ftp.mozilla.org/pub/firefox/releases/127.0/linux-x86_64/en-US/)

But after v127 Firefox always opens files directly (see screen). I can't find any settings to change this behavior. Something has been changed.

I keep back the firefox upgrade so long it was posible for me but 127 is now old and i use the last version 133.0-1.

I'm using Linux (Debian).

Thanks

Firefox Sync and Cloning a Profile to another Device

I want to copy/clone information in my Firefox Profile (Bookmarks, Logins, ..) from one device to another. Once that was accomplished, then I would enable Firefox Sync for the two devices.

Scenario: Device “A” (Profile A): Primary/Original/Source Device “B” (Profile B): Copy/Clone/Duplicate

I understand that if I set up Firefox Sync first and then sync the two devices what I will get is a combination/fusion of the information on the 2 devices, i.e., all the “good” stuff in Profile A plus all the superfluous stuff in Profile B that I would just as soon ignore/delete – which is not what I want. This issue has been raised in a number of other posts on this forum but with no suitable resolution offered (that I could find). I’m wondering if there might be a “work-around” that would achieve the desired result.

So ... would this work?

1) Back everything up first (of course!) 2) Glean any unique information to be preserved (Logins, etc.) from Profile B and incorporate it into Profile A (Profile A now has everything essential!) 3) Purge Profile B

   a) Create a New Profile on Device B (and delete old?)
   b) Delete everything possible from the new Profile B (default bookmarks, etc.)

4) Login to Mozilla account and enable Sync

The idea is to create a “blank” Profile on Device B so that when Profile A and Profile B are Synched together (combined), Profile A remains unchanged, and Profile B is populated with everything in Profile A (a perfect copy!). The result that I want after Sync is essentially A+B=A, the solution of which is of course B=0, hence the focus on creating a "blank" Profile B.

Instead of purging Profile B as above, an alternate method might be to first “pre-load” Bookmarks in Profile B by the usual method of Backing up Profile A Bookmarks and then Restoring them to Profile B. At this point Profile A and Profile B Bookmarks would be exactly the same and Synching the two devices should make no changes to either’s Bookmarks. Logins and other information would still have to be purged, but this could at least be a head start.

Presumably this idea could be extended to more than 2 devices (but with only one being the “Primary”).

Note that I am (myself) only concerned about Bookmarks and Logins, and am thus glossing-over how other information that might be important to others (Browsing History, Tabs, etc.) might be Synched.

Could someone from Mozilla/Firefox with a knowledge of the inner workings of these features please comment as to the efficacy of this “work-around”?

Thanks.

Please be patient with this narrative. I am new to using Firefox Color. The question will be about whether and how one can upload color variations on a theme design concept. I just had an uploaded theme rejected as "duplicate" even though close 25+ color and UI variables carefully changed. I haven't been able to find the right place to ask this question.

About 4-5 months ago after noodling around with the amazing Firefox Color tool, experimenting with changeable UI elements and color controls slowly, I slowly began building a dark theme I'd imagined but never thought I'd be able to build — not knowing anything about current day CSS. After many hours, much trial & error, I eventually landed on the kind of dark theme I'd wanted —with a very different color palette from common blacks and charcoal greys. I learned how to share it with the Marketplace, uploaded it, described it, it was approved. Thumbs up!

Please bear with me, this next part is what I do not understand and need guidance on how to be compliant with add-on marketplace rules. I'm not sure whether I should, or should not, provide links to the themes I am referencing, given my Q turns on color variants of a design scheme.

The past 3 months, having tested my first theme across a wide span of websites, some dark, some light, some wild colors, and also my being a power user of hierarchical bookmark folder dropdowns, I found a number of usability areas where I wanted to improve color UI interactions. This also after testing with my screen at full brightness, and also at night using warm light filtering. Today I set out to make a much better new dark theme, not just improving core usability but really going after a far more pleasing balance with better colors and distinctions to remove any possible distractions from web browsing no matter which site I was on.

Spent 5-6 hours revamping every element color completely, exported my new theme.xpi to the Marketplace, wrote up description, submitted for approval with the title "Dark Subtle Color - 1"; and about 5 hours later it was approved. I named it with #1 because I knew I wanted to also try some different color variations and dub that one as "Dark Subtle Color - 2".

Maybe I messed myself up with a poor naming strategy, but I'm not experienced in the norms & rules here. It is so common in design to arrive at harmony & balance in relationship to dark, medium and light UI values, after careful attention to contrast differentiation, separation, readability in browser default states, hover states, dropdown & popup states, active vs inactive tabs etc. Then one tries new colors for variety, while sticking to the relative color values of that balanced design. I've seen color variations on themes all over the web, from Chrome store to Firefox Add-on Marketplace.

I the time waiting for approval, after analyzing my submitted theme, I decided I wanted to change up the background colors of the Active and Inactive tabs to provide even greater contrast and distinctions, so that when I'm researching and have 20+ tabs open with most of them pushed out of the limited viewport, and I'm skipping between various tabs, when I have to horizontal scroll, my eye can instantly skim and locate my Active Tab ... because it is that bullet-proof different.

Really happy with those new color choices! But one change leads to another, and next thing I am changing and adjusting many more elements. Particularly after I finally dug into and figured out the 15 or so "other" UI color elements listed in the Advanced Colors for which I had previously never understood where the corresponding visual elements were located on-screen.

Yes I began with my submitted "Dark Subtle Color - 1", but I changed all together about 25 color elements -- not like some crazy rainbow world -- many were subtle improvements based on popups, selected URL, bookmark dropdowns, background and text colors, changed the color of icons, changing the opacity of the Bookmark Folder icons and their associated text labels to dial down the amount they popped out in a distracting way. I liked this arrangement very much as well, so per plan I saved the new theme.xpi file and submitted to Marketplace as "Dark Subtle Color - 3". It's a separate theme but to the untrained eye the only standout features would be the new tab-state colors.

So yes I was surprised and taken back when I later get mozilla emails stating my numbered color theme - 3 was rejected, not published: "Our review found that your content violates the following Mozilla policy or policies: - Other, specifically Duplicate: We cannot add your theme to the gallery because we do not permit duplicate copies of existing themes. We appreciate your involvement in the Theme developer community."

My question is: Was my principle error poor NAMING of the last theme? The colors are different! What am I missing about the word "duplicate"? Maybe the rule-set should be really clarified because "different color choices" and "duplicate" are 2 very different things. I spent this time to write this up so that others beside myself can be helped. Rules are always essential, but it seems to me that in pursuit of definitional purity, users are poorly served if color variations on theme arrangments are verboten. Thank you in advance.

Good Afternoon,

I bought a guitar course from this web site, https://masterclass.davidleviguitar.com/users/sign_in, and whilst the page opens up, when I click on any part of it nothing happens.

I then downloaded Chrome and everything works perfectly.

Can you please tell me how to get this site working properly on my computer, as I don't want Chrome on my computer.

I thank you and look forward to hearing from you.

Kind regards.
