How do I make a CSUI container fill the anchor's width and height?
Working on my first browser extension and ran into this issue - I want to have the CSUI container fill anchor's width and height, so I can then use much simpler CSS to position the contents of the CSUI container wherever I want across the anchor element.
In my case, the anchor element is a simple
textarea(I don't need to handle the case where the textarea gets resized)....Opening content script only if an element is present on the page?
I want to show my extension in a sidebar only if a certain value is present in the html of the page. Im looking to show the extension content sidebar only if the json+ld schema matches @article.
I have a scraper function that returns content if it exists (which I already have working perfectly) but lets just pretend for this question that it simply returns a boolean.
for example could this:...

which is a good/scalable folder structure for a big extension?

HMR for other chromium browsers
Is it possible to run a development server for opera, firefox, brave, edge, etc? I tried chaining run commands by specifying a dev target and haven't had any luck.
From what I can tell it's this addition to the manifest that achieves this dev server behavior:
```{...
plasmo dev --target=<some-chromium-target>-dev
plasmo dev --target=<some-chromium-target>-dev
Is there an extension repository that shows how the testing should be done?
Is there an extension repository that shows how the testing should be done? I want to see how the background and content scripts, popup, options, etc tests should be done.
Thank you...

How to access the methods or variables of another third-party extension
hello, is there any way to access the methods or variables of another third-party extension (I suppose these are declared in its content script)?
I want to modify the behavior of a third party extension and it would be easier for me to access its variables or methods, and make small changes to it, or call methods from my extension,than scraping the HTML it adds to the web, or doing everything from scratch
Thanks...
Build time slowed by switching to plasmo with src
Build time with src: ~8854ms
Build time without src: ~1656ms
Is there a build time improvement by not using plasmo with src as shown here: https://github.com/PlasmoHQ/examples/tree/main/with-src ? I recently migrated my file structure to use src and builds are about 5x slower. Any guidance would be great thank you!...

Modifying HttpOnly cookies
There is a specific cookie that I am trying to extend the expiration date of, but I can't figure out how to modify it. At first, I tried modifying it with a
content.ts file that edits the document.cookies, but that doesn't include httpOnly cookies. I then made a BSGW and tried to use the webReqeuest API to listen to the onHeadersReceived event, but that also doesn't include the set-cookie headers. Does anyone have any ideas on how to go about doing this?Local Storage Item does not show up in service worker dev tools ?
I am saving simple key value string (id: "123") in my background script which I'm able to read it (and can console) every time but it doesn't appear on service workers Application/Local Storage I'm not sure if it's expected behaviour or not. I have checked host websites Local storage as well it doesn't show up there as well. Interesting part is that plasmo can read it magically from somewhere
CSS loading order
Hi everyone,
Context: I've built an extension using the
content-scripts-ui [1] template as foundation - specifically the google-sidebar variant. I've kept the same 2 CSS files i.e. google-sidebar-base.css and google-sidebar.css for styling whereby the former is loaded into the parent page (import "./google-sidebar-base.css") and the latter is loaded into the shadow DOM (via getStyle). I've modified isOpen to be closed/false by default.
Problem: The first time the extension is rendered, the styles from google-sidebar-base.css don't get loaded and the extension panel renders on the left hand side and with a smaller width than normal. Once I refresh it, the problem goes and stays away for some time, until I close my browser or if I refresh after some time has passed. Any idea why this might be happening? Feels like a race condition until the stylesheets are cached maybe. Any help would be appreciated....Messaging-chrome.runtime.sendMessage() called from a webpage must specify an ExtensionID (string)

Is there a way to include other icons in the build so that I can customise my extension icon depending on which url I'm on?
In the icon page within the documentation, I can see there are options to include icons for specific builds, however I would like to ask if there is a way to include other icons for the same build?
