LinqSender for LinkedIn: run LinkedIn from your browser

Install in five steps

1. Download and unzip. Unzip it somewhere you will keep, for example Documents. You get a folder called LinqSender-LinkedIn-Extension. The browser loads the extension from this folder, so do not delete or move it afterwards.
2. Turn on Developer mode. Open your browser's extensions page and switch on Developer mode. Where both are, browser by browser, is listed below.
3. Load unpacked. Click Load unpacked and choose the LinqSender-LinkedIn-Extension folder (the one with manifest.json directly inside).
4. Sign in to LinkedIn in a tab, with the account you want campaigns to run from, and keep that tab open while campaigns run.
5. Connect it in LinqSender. Go to LinkedIn → Accounts → Connect → Run from your browser. The extension pairs itself while the connect dialog is on screen; there is nothing to type.

Which plans include the LinkedIn browser extension?

Every LinqSender plan includes it. Each seat runs one LinkedIn account: Starter 1 account, Growth 3, Pro 6, Scale 10, Agency 18 and Enterprise 30. A trial includes what its plan includes.

How does it pace my LinkedIn account?

Our server paces every action within daily limits, with a gradual warm-up and your working hours, the same as every LinqSender LinkedIn account. The extension only performs the actions your campaign has scheduled, one at a time, with natural pauses.

It never stores your LinkedIn password and never reads other websites.

What happens when my browser is closed?

The campaign waits. Nothing is lost, nobody is skipped, and the campaign continues from the next person when the browser is open and you are signed in to LinkedIn again.

Which browsers does it work in?

Chrome, Edge, Brave, Arc, Opera and Vivaldi. Firefox and Safari aren't supported yet. Use Chrome, Edge, Brave, Arc, Opera or Vivaldi instead.

Why was someone skipped with an old-format link?

The extension opens profile links in the linkedin.com/in/name format. Older linkedin.com/pub/ links and Sales Navigator links can't be opened from your browser, so that person is listed on your campaign page instead of being sent to. For example, replace linkedin.com/pub/jane-smith/1/2/3 with the linkedin.com/in/ address you see when you open their profile.

About the "developer mode" notice

Because the extension is installed from a folder rather than a store, your browser reminds you about it. What each browser shows and what to click is listed above. In short, keep the extension on and never choose the option that turns developer-mode extensions off.

Update

Folder-installed extensions do not update themselves. When a new version is ready, this page and the extension tell you.

1. Download the new zip and unzip it.
2. Replace everything inside your LinqSender-LinkedIn-Extension folder with the new files.
3. On your browser's extensions page, press reload on the LinqSender card.

Remove

1. On your browser's extensions page, click Remove on the LinqSender card.
2. In LinqSender, open LinkedIn → Accounts, click ⋮ on that account and choose Remove account.

Troubleshooting

• The extension's card shows errors: download the zip again, replace the folder's contents, and press reload on the card.
• "Extension detected" never ticks: reload the LinqSender tab after loading the extension.
• Keep a LinkedIn tab open and signed in. Campaigns wait while LinkedIn is signed out.
• One browser profile per LinkedIn account.
• If the Developer mode switch is greyed out or Load unpacked is missing, your browser is managed by a workplace or school and folder-installed extensions are blocked. Use a personal browser profile.
