Modifyer key to control behavior of "Modify Content-Type" extension

It would be really handy if you could set modifyer keys to control the behavior of this extension, e.g. holding down Alt/Option key to force a link to be displayed inline, rather than having to configure URL's using regular expressions.

Extension not working

I'm unable to get the extension to work. It's enabled, but doesn't appear to be doing anything. It works for a colleague, but not me, even though we tried identical rules and are using the same version of Chrome (92.0.4515.131). Perhaps something in Chrome is blocking it? I tried another extension that also modifies the Content-Type and it has the same problem. Any suggestions? I've tried disabling all other extensions, tried on a parallel install of Canary, tried in Incognito - but still no luck.

Change type without rule

It would be nice to have an option to change the content type of the current page, *without* having a rule defined (e.g. some drop-down box "Change type to ...").
I have a situation where some pages on the same site work fine, but others need a type fix, so I can't really use a rule for that.

Does not work cross-site?

I browse to a page on and click a link for a file (a jenkins artifact, This redirects to , which then downloads. I've tried and tried, but can't seem to convince the plugin to prevent the download and display instead - I have it set to modify the type from binary/octet-stream to text/plain and set disposition to inline, but no luck.

I was able to use Modify Content-Type before we changed jenkins' storage to s3, so I'm thinking the redirect might break it. If this redirect really is the issue, is there any workaround?

I'd try debugging but I'm not sure that's possible with extensions downloaded from the chrome store. Is it possible to view a log of actions taken/not taken and which regex did/did not match?

Not working as intended

I'm using arcgis server and there seems to be an issue with how the program handles attachments on hosted feature layers. It feeds jpeg images to the browser as application/octet-stream. I found your program and configured a rule for the site but the behavior hasn't changed. I used the following settings:

URL Filter: webapps\.seconnections\.com
Original Type: application/octet-stream
Replacement Type: image/jpeg
Disposition: inline

Am I configuring this properly or did I make a syntactical error? I'm pulling my hair out trying to troubleshoot this. I can't fix this on the server and am waiting for esri to address and patch. Any help you can provide would be greatly appreciated.

Need Proper Content To Make a Rule

What should be the rule to get Chrome to open png files in the browser instead of downloading them?

Simply does not work for me

Maybe I’m making an obvious mistake here, but the following rule fails on Chrome 69/Linux.

URL Filter: /architectonic
Original Type: .*
Replacement Type: application/xhtml+xml
Disposition: <unchanged>

Still I see plain text (wrong) when loading from URL “file:///home/mike/work/wayic/architec/architectonic”.
