[BUG] Org-protocol bookmarklets in Firefox behaving badly after recent upgrade [9.6.15 (release_9.6.15 @ /usr/share/emacs/29.4/lisp/org/)]

[BUG] Org-protocol bookmarklets in Firefox behaving badly after recent upgrade [9.6.15 (release_9.6.15 @ /usr/share/emacs/29.4/lisp/org/)]

Hello all,

After upgrading Firefox to version 133.0-1 on Manjaro Linux, I find that
that my Org-protocol bookmarklets in Firefox are not working properly.

Namely, after I click on them to capture a link or some text, the
information is copied appropriately but the browser switches from
displaying the webpage to displaying an almost blank page with just the
text of an Org-protocol link.

E.g. when using the following bookmarklet

    javascript:location.href='org-protocol://store-link?'+new
    URLSearchParams({url:location.href, title:document.title});

on the webpage https://orgmode.org/, Emacs is able to capture the link
and title ("Org mode for GNU Emacs") as desired, but the browser
displays a blank page with the following text:

    org-protocol://store-link?url=https%3A%2F%2Forgmode.org%2F&title=Org+mode+for+GNU+Emacs

I have to hit refresh to redisplay the original webpage.

The same occurs for more complicated bookmarklets involving Org capture
templates, as well as Org-roam-protocol bookmarklets, but I think the
basic issue arises from Org alone.

I have continued to use the same `org-protocol.desktop` file to handle
these links:

    [Desktop Entry]
    Name=org-protocol
    Exec=emacsclient -n %u
    Type=Application
    Terminal=false
    Categories=System;
    MimeType=x-scheme-handler/org-protocol;

I know that Emacs 29.2 introduced a new `emacsclient.desktop` file that
handles Org-protocol links, but copying it from
`/usr/share/applications` to `~/.local/share/applications/`,
renaming/removing the old `emacsclient.desktop` and
`org-protocol.desktop` files, and running

    update-desktop-database ~/.local/share/applications/

does not resolve the problem.

Interestingly, the `org-capture` extension for Firefox from
https://github.com/sprig/org-capture-extension continues to work without
producing this issue (i.e. the link is captured and the webpage
continues to be displayed properly).
